GL1000 -- Ignition (and other) Upgrades, Part 2

Has it really been five months since I ripped into the Goldwing?!?! I am nothing if not a procrastinator, I guess...Anyway, after a three month hiatus, I finally decided to wrap up the ignition upgrade and cooling system rebuild, since summer has now arrived in Alaska, and I really want to be riding my 'Wing again!

When I was researching the Dyna ignition upgrade, one of the common failure modes of the Dyna was to lose the 12VDC power to the ignition. Dyna recommends taking power from the accessory module under the left-hand shelter cover on '78 model year GL1000's. However, I have seen a short elsewhere in the electrical system take out the accessory power, since the tail light wiring is tied into the same fuse as the accessory power. Furthermore, I'm not too sure I want to power my ignition (where I want really good input voltage and current) from the same source that powers the tail lights, my heated jacket and whatever other electrical doodads I decide to add in the future. On the other hand, I don't really want to completely redesign the entire electrical system on the bike either, particularly now that riding season is in full swing. So, I decided to compromise: I wired up a 20A relay between the battery and the accessory block, triggered by the current that used to power the accessory outlet. If I get another short in the tail light wiring, I'll still be dead in the water, but I've at least got current directly from the battery to the ignition. It's not an ideal solution, but maybe I'll revisit the design next winter.

Once I had power to the ignition, I got started setting the timing. Dyna recommends connecting a test lead to the coil input, but Octane at Naked Goldwings posted a really, really good how-to (registration required, I believe), where he points out that you can simply tap into
these connectors right here to verify your points timing -- much easier than trying to access the coils directly! However, when I turned the key to the "on" position and rotated the engine two complete revolutions, I was unable to get my test light to light up. Okay...how about the other coil? Nada. Hmmm...what gives? The ignition has been sitting in my garage for a little over a year (just long enough for the warranty to expire, @#$%!!!), but I can't imagine that would cause it to fail. After troubleshooting for the better part of a day, I called it a night, and watched YouTube videos of a guy riding a modern Goldwing in Japan for a while, lol. When I woke up the next morning, I had an epiphany: "The ignition is grounded -- i.e., no voltage -- when the run switch is in the 'off' position. You never put it in the 'on' position!" Could that really be it? No...couldn't be. I had completely removed the ignition from the bike and bench tested it! I jumped out of bed, reinstalled the ignition in the bike, turned the key on, turned the run switch on, and was rewarded with a brightly lit test light -- well out of spec for the timing, but at least proving that the Dyna worked! Timing the ignition per Octane's instructions was tedious, but easy. Notice how many times he says, "...the marks on the flywheel should line up...probably don't...?" There's a reason for that, lol.

Once the timing was set, I reinstalled all of the various covers, placed split-loom tubing over the new power wires to the ignition and accessory box, and got started on the next item in my checklist: the air cut-off valve.

This device...actually, I'm not entirely sure what it does, but what I do know is that there are several little rubber o-rings and a slightly larger rubber diaphragm that eventually get brittle and crack, allowing air to leak into your intake system on the wrong side of your carburetors, leading to a lean condition, especially at idle or when using engine compression to slow down. If this happens, you'll hear a burble when you release the throttle -- something I've noticed on my bike. I had picked up a rebuild kit from Saber Cycle (Randakk sells one too, but I found it on Saber Cycle first). On GL1000's, it's really simple to remove: just forward of the air box, under the spark plug wires and next to the #1 carburetor is a small, round metal object with a rubber hose plumbed into it. Pull the hose free, then remove the two LOWER screws (the top two screws hold the cut-off valve together), and lift it up through the shelter.
Rebuilding is almost as easy: remove the top two screws, and carefully pull the cut-off valve open, paying attention to the orientation of the rubber diaphragm (the metal bump should be on the underside of the diaphragm). Use a pick to remove the o-rings, and use just a dab of grease to hold the new o-rings in place while you reassemble the valve. Piece of cake!

With the air cut-off valve rebuilt and back in place, it was time to button up the intake systems, so I replaced the airbox-to-carb gasket, and started to reinstall the airbox. Of course, nothing is ever as simple as you expect, right? Because the Dyna coils I installed are slightly larger than the OEM coils, the installation instructions say "you might have to" cut a short piece off of the intake snorkel on the airbox. I was hoping I could get away without surgery on the airbox, but no. With the airbox about 80 per cent in place, the intake snorkel was pressed up against the towers and upper spark plug wires, so I pulled the airbox free and modified the intake snorkel with my angle grinder. Truth to tell, had I known this was necessary, I probably would have looked for a different set of coils. I know that the GL1000 is pretty sensitive to changes to the intake system, and since my airbox is in pretty good shape, I'd rather not cut on it if I don't have to. Unfortunately, when I bought the coils, I didn't know that the airbox wouldn't fit, so now, given the choice of cutting the airbox or replacing a brand new, perfectly good set of coils, I opted to modify my airbox.<shrug>

Next, I had to figure out how to route the hoses for the crankcase breather. In between garage sessions, I had looked on-line for a diagram that showed which hose ran to the crankcase breather opening and which ran to the drain cup, but was not successful. I figured I could probably figure it out by looking at the lengths of the hoses, since the drain cup sits lower than the breather opening, but as it turns out, the solution was even simpler than that: the nozzles on my airbox are labeled "drain" and "engine," lol, making it extremely easy to determine which hose goes where!

With the airbox reinstalled and the crankcase breather reattached, the next project was swapping out the front wheel. When I bought the bike, the previous owner included a boat-load of spare parts: an extra set of wheels (front and rear), an extra pair of front brake discs, floor boards, a Vetter fairing, an extra rack of carburetors, and I don't even remember what else. Last summer, when I replaced the front tire, I found that the installed wheel was in rather poor condition, with the inside of the wheel gouged up pretty badly by tire irons. I'm not great at replacing tube-type tires, but out of four previous tires (front and rear each on my XS750 cafe racer and my wife's CB750 Hondamatic), I had only pinched one tube.

I punctured THREE brand new tubes while replacing the front tire on the 'Wing, and NONE while replacing the rear tire.

I'm not saying that I can't be as much of a ham-fisted monkey with a tire iron as anyone else, but I find it really hard to believe that I got so lucky with two other bikes (and half of this one) and so UNlucky with the front tire on this bike. Since I also seem to have a slow leak with the tube currently installed on the front tire, I decided to take the downtime on the GL1000 to replace the bearings on the spare front wheel, move the brake discs off the existing front wheel and onto the spare front wheel, install a new rim strip and a new heavy-duty tube on the spare front wheel, move the existing tire to the spare front wheel, and finally reinstall the whole assembly on the bike.

First order of business: removing the old dust seals from the spare wheel, which proved to be far more difficult than you would expect. My seal pullers simply tore the seals, even after heating them with a heat gun. Eventually, I pried into the outside (:eek:) edge of the seal with a tiny, flat-blade screwdriver, and popped the seals off. Gotta love 40 year old parts, sigh. I also mangled the old speedometer gear retainer and the bearing retainer on the other side of the wheel. Note to self: Honda makes a tool especially for removing the bearing retainer, or you can grind one out of a suitably-sized socket. A hammer and screwdriver does NOT make a suitable replacement for the proper tool. Fortunately, Bike Bandit had replacement parts for a not-terribly-unreasonable price...but it would have been cheaper to buy the proper tool. Amazon supplied a replacement set of bearings and dust seals from All-Balls, and a few minutes with a hammer and a large-diameter socket resulted in a firmly seated set of bearings in the wheel. Note to self, again: read the instructions in the Clymer manual before seating the bearings. Only ONE bearing should be firmly seated; the other should LOOSELY rest against spacer between the bearings. You'll know you've seated the bearings too tightly when they won't turn properly. See? I can be just as ham-fisted as the best of them, sigh. I think I managed to solve that problem without ruining the bearing in the process. At least, I hope so, anyway.

Once I had the new wheel ready to go, it was time to pull the old wheel and move the brake disks and tire to the new wheel. Once I started removing components from the old wheel, I got a reminder that this bike is almost -- but not quite -- as old as I am. The five bolts that hold the brake disks to the wheel were covered in white and orange corrosion (aluminum oxide from the wheel, and plain rust from the bolts, I presume), and the axle was coated in a thick, reddish-orange paste of congealed grease and rust. A combination of engine degreaser, a brass cleaning brush and 600-grit emery paper did a passable job of cleaning up the axle, and a wire brush on my drill greatly improved the condition of the bolts for the brake disks.
After getting the wheel and bolts cleaned up, I reinstalled the brake disks on the wheel, ready to be installed after replacing the steering head bearings...but that will the next post ;)

GL1000 -- Ignition Upgrades, Part 1

It's that time of year again, when the world grows quiet under a soft blanket of new fallen snow, when all of the birds, rabbits, squirrels and bears that frequent the woods near my house tuck themselves into their nests and burrows and dens, and when that most unpredictable of species, motocyclist insaneus, retreats into the warmth and comfort of the garage, preparing for the spring thaw only four months away.

In my case, it was New Year's Eve, my wife was pulling an overtime shift at her job, my teen-age daughter was celebrating at a friend's house, and so I decided to ring in the new year surrounded by some of the ones I love, namely, the motorcycles, lol. There were several niggling problems with the Goldwing that I needed to take care of, and therefore, handed a block of several hours in which I could dig into the 'Wing without feeling guilty about neglecting my family, I started the dissassembly process.

First order of business: sorting out the cooling issues. Near the end of summer, I was two-up on the 'Wing in stop-and-go traffic (far more stop than go, to be honest) when I noticed that the temperature gauge was indicating much higher than normal and climbing...quickly. On a test ride, I found the temp would climb when the bike was still or when under load at low speed, but would cool off again when cruising, and I noticed the fan didn't seem to be running when stopped. During dissassembly, I connected the fan to a spare battery, and found that it operated just fine, which was very welcome news since the radiator fan is no longer available from Honda for this particular bike. The next-most-likely culprit was the fan switch, still available from Honda at $$$$$ or from an aftermarket supplier for $$. I opted for the aftermarket part. Since I was digging into the cooling system anyway, I picked up a new, aftermarket thermostat and both upper and lower radiator hoses, as well. Note: the fan switch comes with an o-ring, but the thermostat does not; fortunately, my local Honda dealer, who doesn't typically stock vintage bike parts, actually had the o-ring I needed on-hand. Replacing the old thermostat and fan switch was pretty trivial. By far, the most difficult part was reattaching the rubber boot that contains the fan wires to the fan switch. Hint: reinstall the boot BEFORE reinstalling the water inlet (covering the thermostat).

Next up, ignition system upgrades. When replacing the points in the stock ignition last year, I noticed that the threads in the OEM points backing plate were kind of sketchy. I managed to install the new points (an aftermarket brand that has a reputation for sticking a bit, but all I could still find for the bike), but not trusting the points themselves or the stripped-out backing plate, I picked up a Dynatec electronic ignition and new coils later last year. Because the crankshaft in the Goldwings' horizontally opposed engines runs lengthwise through the engine (rather than below the cylinders as in a typical inline four), you typically use the bolt through the alternator to rotate the crankshaft to set the engine timing. Unfortunately, the alternator bolt on my 'Wing is more circular than hexagonal (hey, it was like that when I bought it!), and therefore, the only way for me to rotate the engine is with the crankshaft nut under the timing belt covers...meaning that I would have to remove the radiator to set the timing.



Because I already had removed my radiator for the cooling system work, this seemed like a good time to dig into the ignition, too. I started by removing the coils, which honestly was kind of a pain, due in no small measure to this junction box and all of the associated wiring.



After a little work (and a lot of swearing), I finally got them free. However, when I started wiring up the new coils...
...I found that the "included" 10-32 x 5/16 pan-head screws and terminal lugs that are used to attach the primary wires to the coils weren't. To be fair, I can't blame Dynatec. I bought the coils a little over a year ago, and I honestly don't remember if there was a hardware bag in the package or not; there's at least as good a chance that I simply misplaced the hardware bag as there is that Dynatec ommitted them from my shipment. In any case, it's easy enough to pick up new screws from the hardware store, and I already had a collection of terminal lugs that I could use, so no biggie.

I had a moment of panic as I prepared to clip the primary wires off of the original coils, when I realized that I had no idea which color primary wire went to which coil. Before removing the coils from the bike, I had carefully sketched out which coil provided spark to which cylinder, but I had neglected to include which primary wire (yellow, or blue with yellow stripe) went to each coil. Fortunately, the high-tension wires to the spark plugs are labeled, "1-2-3-4,"e; and as both the high-tension and primary wires were still attached to the old coils, I was able to determine that the blue/yellow wire goes to the coil for the #3 and #4 cylinders, while the plain yellow wire goes to the coil for the #1 and #2 cylinders:



Sorry, it's a rather poor photo of an even worse drawing, but if you found this blog post while searching for this information, hopefully you'll find it useful, anyway!

Anyway, after finally figuring out which wire to connect to which coil, I crimped terminals onto the primary wires, installed the coils onto the mounts, slid the new high-tension wires into the coils, and reinstalled the whole lot back into the tunnel:



Since this bike is now 40 years old, I decided I'd show some love to all of the electrical connectors that I disconnected to get access to the coils. Sketchy electronics can be a real pain in the a-(hem) to track down, especially on the side of the road, in the rain, at night, when such things are statistically most likely to happen...or something like that, anyway. To do my best to keep the electrons flowing, I pulled out my set of contact cleaners and a spray can of solvent made for, well, cleaning contacts (the electrical kind), and set to work. Once I was satisfied that they were clean (not terribly long, as they were actually in pretty decent shape), I smeared a little dielectric grease on the contacts, and plugged all of the electrical connectors back together...

...at which point, I found a strange, green wire about six inches long hanging out of my wire harness. Ummm, where did that come from??? A quick Google search later, I found that this is a ground wire for the coils that should be sandwiched between the coil mounts and the frame of the bike. I cleaned up the terminal lug on the wire, smeared dielectric grease on it too, then removed the bolt on the top coil mount and attached the ground wire.


All that was left for the coil installation at this point was rigging up the high-tension spark plug wires. I had attached the wires to the coils before installation, marking the wires with the cylinder number so that I could be sure the correct wire was run to the correct cylinder. Now that the coils were in place on the bike, I routed the spark plug wires between the carbs, snapped them in place into the stays, and cut them to length. Installing the new NGK spark plug boots was pretty trivial: spray the wires with silicone lubricant, slide the waterproof seal over the wires (trust me, the silicone lube makes this step MUCH easier!!!), then screw the spark plug boot onto the end of the wire. Once you cannot twist the boot any tighter, slide the waterproof seal down over the boot, and snap the wire in place on the spark plug. I actually intend to replace the spark plugs with new NGK Iridium plugs before spring, but for now, while I'm still connecting and testing everything, I'll leave the old plugs in place (if I mess up a plug while working on the ignition, I'd rather it be a $3 plain spark plug rather than a $10-15 Iridium plug).

Dreams, Perspective and...Maybe Growing Up a Little?

It was the summer of 1986, or so, and I had a part-time job delivering a weekly newspaper in my neighborhood in Maryland. I already knew that, sooner or later, I'd be a motorcyclist, but at this point in time, I was relegated to a BMX bicycle, which was where pretty much all of my meager earnings from the paper route went. While out delivering papers on my route, I started to notice a particular line of Honda motorcycles showing up pretty much everywhere. Some were 500cc bikes, some were 700 or 750cc bikes, and every once in a while, I'd even see a mighty 1000cc version of the bike. Whatever size, I was immediately drawn to the bike any time I saw one. White, with red and/or blue trim, a modestly sized fairing surrounding the single square headlight, and the beautiful V-4 engine on display for the world to see, I thought it was the most beautiful bike I'd ever seen. The bike was, of course, the first generation of Honda's legendary Interceptor, and I was so taken by the bike that, to this day, I still think that the only suitable color for a proper sportbike is white.


When Honda introduced the Interceptor, the press and public alike raved over it. As one of the first generation of true sportbikes, the Interceptor was one of the quickest, best handling bikes around. It truly was revolutionary. As a testament to the job Honda did on the design of that bike, the modern version of the bike lives on in Honda's current lineup as the VFR800, albeit as a sport-tourer rather than a pure sport bike. Nevertheless, it has a devoted fan base, holding its own against such rivals as the Triumph Sprint and Suzuki Bandit.

When I recently saw a 1985 VF700 Interceptor on Craigslist, I packed up my riding gear, drove an hour out of town to the current owner's house, and looked over the bike, thrilled to possibly bring a childhood dream to life. Seeing the bike in person, I was all but sold.

You see, after seven years and roughly 40,000 miles on my V-Strom, I've started to become a little bored with it. I had hoped that either my XS750 Cafe Racer or the '78 Goldwing might deliver a little more performance than the "slow" V-Strom, but the V-Strom has proven to be quicker off the line than either of my other bikes, and absolutely eats up the vintage bikes in the handling department. Something a little sportier, a little sexier, a little more exciting was what I was hoping to find with the Interceptor, and so far, things were looking good. I was about ready to hand over the cash for the bike, but first, a quick test ride to make sure it really was working as advertised. I fired up the engine, and my-oh-my, what a glorious sound that emanated from that beautiful V-4 engine! I put the bike in gear, feathered the clutch and rode down the block onto the highway, and...

Meh.

When I rode the Interceptor, I felt like I was on my familiar, somewhat stodgy V-Strom. Sure, the riding position was a little sportier, but I was profoundly disappointed by the performance. This bike was a legend, groundbreaking. It was the stuff of some thirty-odd years of dreams. And it felt almost exactly like my old, faithful standby. There was no rush of adrenaline when I spun the throttle. It tracked around corners well enough, but didn't exactly carve them the way I expected a sportbike -- even an older sportbike -- to do. It was good, solid...but not terribly exciting.

I walked away from the sale, feeling rather depressed.

A few days later, I had a bit of an epiphany. The problem was that I had essentially started my motorcycle life on what truly is an amazingly good motorcycle, but since that was all I had ever known, I was taking it for granted. Before I bought the V-Strom, I spent hours studying the bike on-line, reading every review and magazine article I could find. While a lot of owners were somewhat self-deprecating about the bike (I'd heard the term, "old fart's bike" thrown around quite a bit on the Stromtrooper forum), most of the actual reviews I'd read were overwhelmingly positive. Having owned mine for so long, I'd have to agree with the reviews. My V-Strom has handled every combination of poor roads, ham-fisted rider technique, crappy weather and bad judgment that I've thrown at it, and despite all of that, it has never, not even once, stranded me anywhere. With its somewhat bulbous front fairing, it is perhaps not the sexiest bike ever made, but it has been nothing less than an excellent motorcycle, and after riding the Interceptor, I began to realize just how little credit I had given my bike, and to some degree, how much I had built up the Interceptor in my mind.

I once read that sometimes fantasies are best left unrealized. The Interceptor, my two-wheeled fantasy since before I was old enough to even have a license, will remain just that, I think. It's a beautiful motorcycle, with an amazing exhaust note, but I wouldn't trade my V-Strom for one.

As for something a little sportier...well, a few weeks later, my wife pointed out another ad that she found on Craigslist, and now, I'm the proud owner of a low-mileage, 2006 Triumph Speed Triple:


...but that's another story for another day. For now, I have two brand new tires and freshly-installed braided steel brake lines on my V-Strom. It's time for a post-maintenance shake-down ride :)

GL1000 Project, Part 6: It's Alive...and then Not So Much

After lots (and lots, and lots...) of effort, I finally managed to get a complete, working set of brakes on the Goldwing: three calipers ordered from E-Bay (after the original set that came with the bike), three master cylinders (on the plus side, I now have two that I can rebuild :/ ), two sets of brake lines, a boatload of bleeder valves...but the brake system finally is working properly.

Painting was only slightly less of a chore. I kept running into weird problems with the paint crinkling up on the plastics and on the crash bars. I tried everything to solve the problem. I tried pre-heating the paint and the parts, since it was near the minimum recommended temperature when I was trying to paint everything. I tried cleaning the parts with soap and water before painting. I tried cleaning the parts with denatured alcohol before painting. I tried cleaning the parts with brake cleaner before painting. I eventually tried two different kinds of paint on the plastics, and bought some spray-on Plasti-Dip for the luggage racks and crash bars. Finally, I figured it out: the inside of the plastics -- which I hadn't bothered cleaning -- was greasy, and I was picking up the grease on my gloves, which then contaminated the surface before I painted it. Then, after finally getting a good coat of paint on the plastics, I left a handprint on the shelter covers, due to trying to install them before they were completely dry (pro-tip: "handle after 1 hour" only applies in 70+ degree weather; at 55F, with several thick coats of paint on the parts, even 2 1/2 hours isn't long enough).

Finally, it was rideable. On a sunny, April afternoon...

...I wheeled the Goldwing out of the garage, pulled the choke, flipped the kill switch and fuel valve to the "run" position, turned the key to the "on" position, and thumbed the starter button. With a polite, subdued rumble, the 998cc horizontally opposed four-cylinder engine purred to life. I toed the shifter into first, twisted the throttle slightly, gently released the clutch lever, and started rolling down the steep, gravel covered driveway in front of my house.

Having never ridden a motorcycle this large or this heavy, I was a little nervous at first, but quickly relaxed and started to enjoy the bike. The engine was willing, but civilized. The steering was a bit odd at low speeds, but not bad at all at speed -- stable, definitely biased more towards "touring" than "sport," while still being plenty maneuverable for commuting. The brakes...were adequate, but not much more than that. This is not a bike that will be doing stoppies at red lights <shrug> but they're good enough, I guess. I spent a half hour or so tooling around the roads near my house, getting used to the feel of the Goldwing, and trying to figure out what I still needed to tweak.

The bike proved to be rock solid, and a month or so later, my wife and I rode it two-up in a group ride to Kenai, a total of 345 miles over two days. It never missed a beat:



Then, a week or two after the group ride, I was in another group ride out to the Mat-Su Valley, and (fortunately!) after breaking off from the group on my way back home, I pulled the clutch lever in to shift into second gear...and felt the clutch abruptly lose all tension. I did a clutchless downshift, and pulled over on the side of the road to investigate, finding that the ball end, which I had soldered onto the end of the clutch cable after shortening the cable to fit the Superbike handlebars, had fallen off:


I contacted Motion Pro to order a new clutch cable, since they had done such a good job on the cables for my XS750, and was somewhat taken aback to hear an estimated turn-around time of 3-5 weeks. Honestly, however, I wasn't terribly upset by the estimate. I had (twice) blown the fuse to my turn signals, as well as (twice) frying the electronic flasher unit, so I decided to take the time to clean up a few odds and ends that had cropped up during the last few weeks. I'd been having so much fun riding the 'Wing that I had deferred fixing the annoying little bugs -- like inoperative turn signals -- that had cropped up. If the bike was going to be off-line for a few weeks, I'd take advantage of the down-time to start cleaning up some of these items.

The bane of any vintage bike owner is the "previous owner" (P.O.), invariably a ham-fisted monkey without proper respect for the classic machinery (s)he used to own. Yes, I'm fully aware that I have been -- and will again -- be someone else's P.O., and no doubt, they will curse my name over brews in the garage while trying to decipher what could possibly have made me think that <fill in the blank> was a good idea. Nevertheless, this was exactly what I did while digging into the tail light wiring. First, there were three identical, blue wires that were routed into the tail light housing that had the ends wrapped in electrical tape...but connected to absolutely nothing. I fished the wire out of the tail light housing, and traced them to this little box here:



Consulting the Great Oracle of Google, I found that it was a tail light controller for a trailer. Apparently, at some point, someone had pulled a trailer with the 'Wing...or at least, had considered pulling a trailer. Not expecting to ever do likewise, I removed the box, and cleaned up the associated wiring. Next, I found the likely cause of the blown fuses and turn signal flashers:


The OEM turn signal wiring had been replaced with new wires, but the new wires had not been routed through the sheathing that the brake light wires ran through, and the grommet that protected the wires where they passed through the steel fender was missing. During the intervening years, the replacement wiring had chafed on the fender, wearing through the insulation, and causing a short circuit. I fished the turn signal wiring out also, and ran new wire to the tail light housing, this time, protecting the wiring with a new rubber grommet.

While I had the wiring exposed, I decided to replace the rear turn signals with a new set of aftermarket signals that more closely matched the front turn signals. The rear ones worked fine, but I didn't like the cobbed-together look of large, round, chrome OEM rear signals with small, rectangular, black front turn signals. Unfortunately, the new signals meant I had to make some modifications to the license plate holder, but I'm reasonably happy with the final results:


Now, if Motion Pro would just hurry up with that new clutch cable. The 'Wing's been down for over three weeks, and...I miss it! ;)

Animation of Some Cool Weather Near Flattop

There was some interesting weather up near Flattop on the way home today, so I took a detour, capturing a series of photos with my cell phone that I stitched together into an animation:



Call me weird, but I love riding in misty, moody weather:



Maybe it's because of all of the family trips in the mountains of Japan when I was a kid <shrug> I dunno, but while it may be more fun to ride on warm, sunny days, there's something about fog and mist in the mountains that I really enjoy.

GL1000 Project, Part 5: Brakes, Shocks, Brakes, Handlebars, Brakes, Electrics, Brakes, Plastics, and...Did I Mention Brakes?

It's been a while since I updated the blog with the latest on the GL1000 project, even though I've kept fairly regular posts at Naked Goldwings (not remotely as risque as it sounds, lol). In honesty, even though I've been busy with the bike, there wasn't much going on that makes for interesting reading, so I hadn't posted much here. However, I figured it was probably about time to submit a new update.

First, at Christmas, my family offered some support with the Goldwing project by giving me gift cards to Dime City Cycles and Bike Bandit. My younger brother even ordered the Oregon Cycle Parts regulator/rectifier I needed for the 'Wing (thanks, Nick!). One of the parts I ordered with the gift cards was a set of Renthal "Superbike" handlebars, which look pretty phenomenal on the bike...although, in all honesty, i probably should have gone with the Euro bars, as the Superbike bars are probably are a little too low (there's interference between the throttle cables and the instrument cluster on the tank, and I had to re-route the brake line to get it to fit).

Lower handlebars mean control cables need to be shortened, so taking a queue from a tutorial on Naked Goldwings, I shortened the clutch cable. The throttle cables might be a little more difficult, and since they seem to work okay as-is, I've left them alone for now.

Then the brakes...

I hate working on brakes. It's messy, frustrating, and there are so many opportunities for things to go wrong.

The previous owner had told me that he had had trouble bleeding the front brakes. After cleaning the brakes, I saw why. It's a little hard to see in the photo, but that's a crack in the slave cylinder on one of the brake calipers. I went to E-Bay, found a replacement RH front brake caliper for a '78 GL1000, cleaned it, installed it, and found that...it was actually a left-hand piston on a right-hand bracket.
Since it's kind of hard to bleed brakes unless the bleeder is at the top of the caliper, and putting a LH cylinder on the RH side puts the bleeder hole near the BOTTOM of the brake cylinder, I needed a set of banjo bleeder bolts. Off to Blair at SV Racing Parts, who had sold me just such an animal for my V-Strom a few years ago. After installing the banjo bleeders, I found that I still couldn't bleed all of the air out of brake system because my left-hand caliper was leaking around the bleeder hole. I removed the leaking LH cylinder, moved the cylinder on the RH bracket to the LH side, and ordered another RH cylinder for a '78 GL1000...except that it wasn't for a '78 GL1000.
It might be for a '79 GL1000, or it might be for a GL1100 (Naked Goldwings wasn't sure which), but the cylinder was larger in diameter than the '78 GL1000 cylinders I had, so neither my rebuild kit, nor my new stainless steel brake pistons fit in the replacement cylinder. Grrrr... Back to E-Bay for yet another RH cylinder for a '78 GL1000. After cleaning and installing this cylinder, I found that I was still having leaks around the bleeder holes, so I went to Bike Bandit again and ordered new speed bleeders. Oh yeah, somewhere in there, I found that the P.O. hadn't properly reassembled the master cylinder when rebuilding it.
I didn't feel like trying to figure out what was wrong with the master cylinder, so I installed the spare FZR750 master cylinder that I had originally bought for the XS750 project (and ultimately ended up replacing with a new master cylinder from Mike's XS). Even after all that work, I'm still trying to get all of the air out my brake lines, but I'm getting there...I think. Maybe.

My wife and I received an unexpected bonus recently, so I splurged on the Hagon 2810 TTSA shocks that I had been eyeing.
I got the LH shock installed easily enough, but ran into a snag on the RH side. The bushings were pretty cold from sitting outside in the mailbox all day, so they were a little stiff while trying to slide them over the stud in the frame. Consequently, I used two washers and the acorn nut to press the shock into place on the stud.

Unfortunately, I ended up galling the threads on the stud by doing this, and when I tried to remove the acorn nut, I sheared the threaded portion off the rest of the stud(!). I did a little research, and found a guy who had had a similar problem on a GL1200, and he managed to repair the damage by drilling out the center of the stud, tapping it, and then installing a bolt to hold the grab rail and shock in place on the stud. Since the stud is hardened steel and provides support for the suspension, the bolt is non-structural -- it simply serves to keep everything in place while the stud carries the load. To that end, I've drilled out the stud, and now simply need to find a tap of the appropriate size (10mm or 3/8 inch -- whichever I can find locally).

On a cosmetic front, I've pulled the crash bars, passenger grab rails, and the side covers and started blacking them out. For reasons I'm not going to go into here ;) I'm going for the stealth look on this bike. Yeah, I know...it's cliched, and high-viz is more likely to keep stupid cagers from doing their inadvertent best to kill me. However, bright orange on my (tall!) V-Strom hasn't done much to make me noticed (last summer, I actually had a cager pull up next to me to tell me that he didn't see me pull out of the side road until he was almost next to me, sigh...), and I like black, so I'm blacking out the bike as much as I can.
The OEM paint is easy enough to strip from the side covers, and ABS cement seems to do a pretty good job of filling the holes where Honda mounted the "GL1000" badges.
The crash bars were moderately scuffed and lightly corroded in places, so a little quality time with a power sander went a long ways towards getting them ready for paint.
The passenger grab rails were a lot cleaner, and therefore, I was able to sand them by hand with a finer grit sandpaper before painting. Unfortunately, the crash bars and grab rails were a little awkward to work with, especially since it was starting to get dark while I was painting them, leading to a couple of runs in places, and a couple of areas of incomplete coverage. I'll have to lightly scuff them this coming weekend, and put another couple of coats of paint on them. Nevertheless, I'm pretty happy with how they are turning out.

There's still a ways to go, and spring is rapidly approaching. However, I think it's getting there. Just...brakes, sigh ;)
