XS1100: Steps Toward Resuscitation

Snow last night, the XS got some mechanical
attention today as a result.
After looking over some internet advice (sic) on how to start a long dormant motorcycle engine (and ignoring never ending discussions on it), I got the XS1100 to the point where it would crank over (with spark plugs removed).  The plugs look brand new, but sooty.  Cleaning them up and regapping should be all that's needed.  It's nice to know it isn't seized, the electrics aren't pooched and the starter motor sounded solid.

I also have the airbox off and the carbs cleaned (though they look pretty clean before I did them).

The gas tank is a rusty mess, it was left outside and empty for a length of time.  I'm thinking about doing some instructables chemistry on it, just to try it.  Failing that, I think I'm going to try Evapo-Rust.

Here's what it looked like today:



Makes you wonder how many motorcycle tires don't get worn out before they need a change.

With the airbox removed, the wall-o-carbs is easy to get at.

Carb internals look to be in good shape.  Only the throttle cable is suspect.


The air box has cleaned up nicely

Getting Connie Back On Her Feet

The front wheel is off to replace
the speedometer gear housing.
So far the cost in parts has been only about $85 for a new speedometer gear from my local Kawi dealer: Two Wheel Motorsport.  Other than that it's been a matter of checking connections and adjusting some poorly run throttle cables.

The gas gauge (reading low/inaccurately) was a loose electrical connection under the tank, cleaned up and connected properly it took about five minutes.  The temperature gauge was similar, just cleaning connections at the sensor (on the left side of the radiator) resolved that.

The speedo was a bit of a puzzle.  I got a new cable assuming the old one has seized (only about ten bucks), but it didn't resolve the issue.  Putting a drill on the cable had the speedometer showing 70km/hr accurately.  The odometer and trip meter both register too, so it wasn't an issue with the gauges.  I looked at the speedo gear housing in the front hub and it didn't spin even when the wheel was.  Robert on the Two Wheel parts desk said these seize up if not lubricated well - they also seize up if the bike wasn't run for a while (as mine wasn't).  He said to make sure I grease the end well when I install the new one.


Well lubed and routed properly, the
throttle cable snaps back perfectly.
The new part should be here Friday.  The local dealer cost about five bucks more than online, but didn't charge me thirty plus bucks in shipping and customs costs, so that's a clear win for buying OEM parts from your local dealer.

The sticking throttle was a matter of taking the cable ends apart at the handlebar and lubing and re-routing them properly - the return cable didn't look like it was installed properly on the higher-rise custom bars on the bike.  After lubing the cables and cleaning the handlebar mechanism I routed the return cable in the proper spot behind the pull cable.  It was tricky getting it all back together again, but once it was done up the throttle was tight, smooth and snapped back like a champ.

I'm hoping to have the speedo done in the next couple of days and then put the bike together for a safety next week.

Chain and no Agony

Follow up to Chain & Agony and How to Size and Replace a Motorcycle Chain...


The whole process of breaking the chain and installing it took about half an hour this time around.  The o-ring chain I got was easy to break using the tool I picked up, and installing the new master link on the chain took only moments.  The three in one DRC Chain Tool I got (chain breaker, outer plate presser, rivet presser) was easy to use and looks good doing it.  It might be my favourite tool at the moment.


The chain-breaking tool comes with two sizes of /privet pushing bit.  The blue bit was for 500 sized chains (the Ninja's is
a 520).  You back off the big bolt and install the push pin, then use the smaller outer bolt to push the pin into the rivet on the chain. The tool automatically centres the rivet, so you're true all the way through.
The new chain was a 120 link chain, the Ninja takes 114 links, so that's 6 links off the end.  The hole in the
top is where the chain pin falls out once you've pushed it through.
Close-up of the blue chain bit .  There is a pin inside it that the outer bolt pushes through, pushing the rivet
right out of the chain.  Once the pin falls out the chain falls apart.  You end up with a clean break and two
inner chain links ready to be re-attached on the bike with a master link.
Six links of the 120 link chain removed.  One pin is pushed right out, the other was pushed
out far enough to dismantle the chain.
I installed the master link on the sprocket - it keeps everything lined up and made installation easy.  After
pressing on the side plate (gently, checking that it's in line with the other links and the chain has play in it),
the only tricky bit was installing the retaining clip, it took a few tries.  When you get it though you know for
sure because it makes a very satisfying click.
With the chain back on and lubricated, everything is tight.  The change to how the bike feels is subtle
but very satisfying.  The engine feels much more firmly connected to the back wheel now.  No sags and tight
spots like on the old chain.

I got this mighty DRC Pro chain
tool
at Royal Distributing in
Guelph
.



Now that I've got a handle on this and the right tools for the job, chains don't worry me any more.  This process also emphasized how surgical bike mechanics are.  I started off doing heavy equipment repair as a millwright and then did a couple of years in automotive.  Compared to that kind of work, motorcycle mechanics feel more like surgery than butchery.  Patience and a careful hand are more important than brute force.

Now more than ever I'm looking for an old bike to dismantle and rebuild to get an inside feel for how motorbikes go together.
