Miscellany

Mid-winter a few years ago, a co-worker asked, "What do you do for fun, once the riding season is over?" Having just acquired the XS750 project, I replied, "There are two seasons in Alaska: riding and wrenching." I don't like to waste my riding season working on the bikes, since the riding season is short enough as is, and invariably, once I start working on a bike, I'll end up with it off-line while I'm waiting for parts to arrive. On the other hand, I do enjoy tinkering on the bikes, so taking them apart to perform all the maintenance and upgrades during the off-season -- when I can't ride, anyway -- is a good way to spend the cold, dark winter months. To that end, I have thrown myself into work on all three of my bikes over the last two months.


In August, I rode my ultra-reliable V-Strom to work one morning, and noticed that it was acting funny while I was idling at a stop light. The turn signals were kind of flickering rather than blinking, and the engine seemed to be running rough, which is very unusual for that bike. I revved the engine a bit, and it settled down, leading me to think that I had a dead battery. That wasn't particularly surprising, considering that it's still the original battery -- six seasons old, now. After work, sure enough, there wasn't enough juice to start the engine. Fortunately, a co-worker was able to jump start me, and I made it home...but just barely. I needed the bike running ASAP, since our motorcycle organization had an event that weekend (this was a Thursday), so rather than taking the time to perform full diagnostics, I jumped to the most likely cause -- a dead battery -- and bought a replacement the next day. After work, I plugged in the new battery, started the engine, and connected a multi-meter to the battery terminals, reading 12.3VDC...not good. I should have been reading just over 14VDC. I took the Yamaha on the BACA event, then ended up ordering both a replacement voltage regulator and stator...at which point, I found that I also needed a gasket for the stator cover, since the V-Strom drips oil onto the stator to keep it cool. I believe I already mentioned something about invariably waiting for parts, once starting a maintenance project?

...all the while, I'm riding the 5000-RPM-idle cafe racer to BACA events...

...an hour away from home, one-way...

...in the rain.


The cafe racer is a fun bike, but with clubman handlebars and NO fairing to protect from the weather, while wearing leathers only in the rain (no rain suit, because my orange nylon rain suit does not exactly scream, "I am a bad-*** biker, and can keep you safe from those who mean you harm") at maybe 40F...not so much.

I was really missing my fairing, my heated grips, and my heated jacket liner, lol (fine, I'm a wuss; what's your point?!?!)

Then, on yet another cold, rainy day on the cafe racer, I started having problems getting the bike into first gear. I could shift into neutral, second, third, etc., but I had a bear of a time getting the bike to downshift into first at intersections. In frustration, I parked the bike, and caged it with my wife to escort one of our BACA kids to court, then when I got the chance to check the Yamaha Triples web site, I discovered that the XS750's have a tendency to break the layshaft bolt, which then causes difficulty shifting into first gear.

Great...with maybe three weeks left in the riding season and BACA Anchorage getting busy working with kids, I had not just one, but *TWO* broken bikes. The whole point of having a second bike was to have an alternate in case a bike broke down!

With the Yamaha now out of service, I jumped into high-gear trying to get the electrical problems with the V-Strom sorted out, since fixing the charging system seemed like a more manageable task. Yeah...no. After finally getting it all put back together again, I took the Strom out for a 10:00 p.m. shake down ride. I was elated for the first eight miles, as the cheapie Amazon.com volt meter that I had plugged into the accessory electrical socket was showing a steady 14.4VDC while riding. Then all of a sudden, I noticed that my voltage was dropping: 13.7V...13.6V...13.5V...about a tenth of a volt per second, more or less. I quickly whipped a U-turn and raced back home...12.9V...12.8V...7.0V. Wait, what?!?! 14.0V...12.2V...13.1V...I started seeing wild voltage swings all over the place, and my LCD panel on the bike had gone completely blank. The engine was running rough again -- the ECU wasn't getting good voltage, so the fuel injection was getting squirrely -- and I just barely made it home (the bike died in the driveway). I opened up the bike -- AGAIN -- and determined that the brand new regulator/rectifier had failed. I parked the Strom, because quite frankly, I was completely fed up with it. I had sunk $450 in parts on the V-Strom in the last two months, and it STILL didn't work right. I spent the rest of the season riding my wife's CB750A to BACA events, and caging it to and from work, sigh.

Fortunately, this was the point that I found the GL1000 project, and I had so much fun working on this bike, that I eventually built up enough motivation to dig into the V-Strom again. Electro-Sport made good on their warranty of the regulator/rectifier, which I re-installed last night, and which now seems to be working properly.


Then, I managed to obtain spousal approval on a pair of Dime City Cycles mufflers for the Yamaha, which are now sitting in the garage, waiting for me to fabricate new balance tubes and connecting pipes to the existing headers. After that, I'll need to drain the oil and dig into the transmission case to replace the layshaft bolt. Oh, yeah...and I've got an envelope full of carburetor parts -- butterfly shaft screws, butterfly shaft seals, circlips, and springs -- for the XS750. Hopefully, those will resolve the high-idle problem on the cafe racer; if not...new carbs?

As for the GL1000...it needs a new voltage regulator, too. Unlike the V-Strom, the 'Wing uses a separate voltage regulator and rectifier, but most of the after-market units I have found seem to be integrated. Oregon Motorcycle Parts makes a reasonably priced unit that seems like it would fit the bill quite nicely, and in my initial conversations with them, they seem to be pretty good people to work with. I expect to have their VRRPM3H-GL1000 model on order in the fairly near future. After that, lower handlebars (so I can connect the front brake line), and a new battery...and the GL1000 should be running! I still want to replace the rear shocks with Hagon 2810 TTSA's, like I did on the Yamaha, and I'd like to order new side covers and shelter covers from E-Bay, because I'd like to go satin black on the 'Wing, but I don't want to ruin the original plastic, since it's in reasonably good shape. However, that's all wish-list material, not necessary-to-get-the-bike-running items ;)

Too Much Wrenching, Not Enough Riding!

I can't believe it's already July.

Summer came early to Alaska this year. Usually, it's the first week of May before enough ice has melted off my driveway for me to be able to get the bikes out; this year, I was commuting to and from work by mid-April. The weather since then has been phenomenal too, with June being a long series of clear, blue, sunny days with temperatures as high as I've seen them since I moved to Alaska some twenty-odd years ago.

So, of course, I spent most of the month of June laid up with an injury that kept me off the bikes entirely during the best two weeks of the month, and then spent the remainder of the month just commuting back and forth to work. I'm almost recovered now, but as a result, I have only taken the Strom out of town once this summer, for the B.A.C.A. 100 Mile Ride. Sigh...

However, even if I haven't been riding as much as I'd like, I've been making progress on the Cafe Racer project. After blowing the head gasket on the Yamaha triple last summer, I picked up a new engine gasket kit from Athena and rebuilt the top end of the XS750. While I had the engine apart, I borrowed an ultrasonic cleaner from a co-worker, disassembled the carburetors, and cleaned the carbs (again...) to try to solve the high idle problem I've been fighting since I bought the bike. After ultrasonically cleaning the carbs, I noticed a ridge of gum inside the carb where the butterflies close, so I did some heavy-duty cleaning on the inside of the carb and the outside edge of the butterflies with some 1500-grit sandpaper, but still can't get the bike to idle properly (grrrr...). I also tested moving the needle valve clip to the stock position (the center position of the five possible settings), but the bike feels like it lost off-idle response and stumbles upon initial throttle input now, so I'll be moving the needle valve clip back to one setting above stock (one setting more lean).

One minor problem I noted with the Cafe Racer last summer was that the front forks felt rather soft -- not surprising, since I have no idea if the fork oil had *ever* been changed. Consequently, I purchased a set of Progressive 11-1107 fork springs from Amazon.com, and rebuilt the forks this past weekend, which turned out to be a much simpler task than I expected, once I figured out a couple of tricks to getting the forks disassembled:

  1. Don't Remove the Forks Completely:
    To remove the fork guts, you'll need to remove a spring clip in the top of the fork. The service manual says to hold the fork tube in a padded vise, then depress the cartridge inside the fork to pop the spring clip loose. I didn't have a padded vise, but was able to make do by lowering the fork in the triple clamps until only about an inch of the fork stuck up above the lower clamp, then tightening the bolts on the lower clamp. Then I used this tool here...:

    ...to depress the cartridge inside the fork...

    ...so I could pop the spring clip loose with a small screwdriver like so:

    NOW go ahead and remove the forks completely for the rest of the work!
  2. Pry Out the Oil Seals from Underneath:
    The next problem I ran into was getting the oil seals out of the fork bottoms. I spent a while trying to dig the oil seals out from the top before finally using the biggest flatblade screwdriver I owned as a pry bar to pop the oil seals out from underneath. Set the blade of the screwdriver under the oil seal, then place the shaft of the screwdriver on the top of the fork. Press down on the handle until the oil seal rotates 90 degrees in the fork, then pull it out with your finger. Easy ;)
  3. Make Sure You Have New Dust Seals:
    I didn't pick up new dust seals before starting on the forks. The dust seal on the right-hand fork looked to be in decent shape, so it probably would be fine, but since the left-hand dust seal is cracked and in pretty rough shape, I'll probably just replace both...once I get a new set of seals...which means I'll have to remove the forks from the triple clamps again in a few days or weeks :roll_eyes:
  4. Don't Forget the Washer Between the Springs and the Pre-Load Spacers:
    Yep, I forgot to install my spacer, so I had to partially disassemble the forks again. Fortunately, this gave me the opportunity to snap the photos above, since I didn't take any pictures at all the first time ;)
  5. Use a Torque Wrench to Tighten the Triple Clamps:
    Otherwise, you end up with a problem like this:

    Yep, I over-tightened one of the bolts and sheared it in half. Fortunately, it was easy to drill out from behind, so tomorrow, I'll pick up four new bolts (might as well just replace them all) and finish up the fork work.

Really, those were the only significant "gotcha's." Everything else was pretty straight-forward. Progressive included a piece of plastic tubing to use to set your spring pre-load with their kit, which means you have to cut the tubing to size for your application. They give measurements for a number of bikes, but unfortunately, the XS750-2D wasn't one of them. However, the XS850 was, and the size recommended for the 850 (1 1/2 inch) was almost exactly the same as the difference in length between the OEM springs and Progressive springs, so I used that. I haven't had a chance to test ride the bike since installing the springs because I can't kick start the bike right now (the aforementioned injury that had me laid up for most of June), and I've removed the electric starter, so kick-starting is the only option for firing up the Yammie. However, once I get a chance to test ride the bike, I'll edit this post with an initial impression on whether or not 1 1/2 inches of pre-load was a good call.

I also might have to revisit the amount of oil I added to the front forks, since I was a bit confused by Progressive's instructions on the subject. After reading and re-reading the instructions, then trying to figure out how to use the Motion Pro fork oil measuring tool, I think I added the right amount of fork oil, but I'm not certain. Again, once I get a chance to test ride the bike, I'll adjust the oil level as required to get the compression and rebound damping reasonable.

XS750 Project Part 25: On Rat Bikes, Abandoned Projects and Moving the Soul

I took an English class in college that was easily one of the biggest wastes of time in my entire college career. However, there was at least one grain of wisdom that the English professor teaching (ahem...) that class left with me: "A work of art is never completed," she said. "It is merely abandoned." Her point, of course, was that you can spend an entire lifetime rewriting, editing, altering, adjusting and perfecting your writing -- or any other art form, for that matter -- and there will still be something else in that work that you feel you can make better. Eventually, however, most artists (writers, painters, sculptors, whatever) grow tired with a particular piece of work, and move on to a new project.

Likewise, I have reached a point in my cafe racer project where, even though I know full well that the project is not complete, it is at least at a point where I can pull it out of the workshop and start enjoying it.

Don't be misled; it's still a rat bike in every sense of the word. The seat is a 1/2 inch thick sheet of foam rubber crudely carved (more or less) into shape and held on to the metal seat pan with bungie cords. The exhaust is shot and falling apart. The bike still idles at 4000 RPM once it has reached operating temperature, although I've got a lead on what needs to be done to fix that (thanks, Gatlyn!). The instrument cluster is dented, the triple trees are faded and rusting, and the idiot light panel is cracked and off-kilter. Nevertheless, it is at least ridable now, and I've been commuting around town on it every chance I get.

As I've said before, the V-Strom has been a great bike, and I am really glad that I bought it. It's rock solid, bulletproof, and as reliable as a bike can be. I've put just shy of 30,000 miles on it in the five summers I've owned it, and I fully intend to ride it into the ground; I don't expect that I will ever sell it.

However...have you ever had an itch where it doesn't matter where you scratch, you can't quite seem to reach it? You scratch here, but it's a little too low. You scratch a little higher, but that's not quite it either. You scratch to either side, but still miss the itch. Desperate now, you scratch all over, but every time, you get close...but not quite there. That's what the Strom has been like. It's a great bike, and I really enjoy riding it, but there's still something inexplicable that's missing when I ride it.

Then there's the Yamaha. Now that I've got it running, I think I've finally found what the V-Strom was missing: Character. Soul. That invisible, unquantifiable, visceral feeling of rightness that you can't explain to anyone else, but that you know and recognize the second it's there. The V-Strom is fast enough; in fact, I've ridden it about 10-20 MPH faster than I've (yet) gone on the Yamaha. It's a lot more comfortable than the Yam. I rode the Strom from Anchorage to Seattle and back, a round trip of 5,000 miles, at least according to the odometer (which, admittedly, includes commuting while in Seattle); the longest round-trip I've made on the bike I've named "Miami" ("My Yammy," lol) is 60 miles...and then I was a little stiff for two days afterwards! The Strom has never, ever stranded me anywhere (although I did trailer it back from Valdez this summer after what turned out to be a non-event -- the chain guard had loosened and was rubbing on the chain, but I thought it was bearing problems again), but I've had to call for a ride home once already while out on the Yammy, and I had to stop and troubleshoot on the side of the road once after the engine abruptly died on me. The Strom is more nimble, turns quicker and is more responsive to body language than the Yam. It also is lighter, has more range, carries more cargo, is more versatile, and starts with the push of a button every...single...time whereas the Yamaha is a cranky, cantankerous, kick-start-only machine, etc., etc., etc.

Yet somehow, despite all of the logical, rational, practical reasons why the Strom is a better bike -- and it is, no doubt about it -- the Yamaha still elicits more smiles per gallon than the V-Strom. When I want to unwind, it's the bike I gravitate towards, even in its present, unfinished state. When I close my eyes and picture myself shedding the stress of the day, the vision in my mind's eye is me astride the Yammy. The Strom transports the body, but the Yamaha transports the soul.

And in the end, that's why I ride. There's nothing logical or rational or practical about it. It's about feeding the soul and feeling alive. Both bikes fill needs that I have, so both bikes will continue to be ridden. Sometimes the mission will be practical, and I'll take the Strom. Sometimes the mission will be emotional, and I'll take the Yam. And if one or the other bike is down for maintenance, at least I won't be caging it during Alaska's all-too-short riding season ;)
