My bike is a 97 california model; with the funny charcoal canister tank vent.
If I sustain 50+mph or wind it out a bit (climbing hills is an easy way to do
this, as you all know) it'll just start stuttering for a few seconds and then
just quit. It happened to me the first day I rode it and I ended up pushing
it home because it wouldn't start back up; it then started 1/2 mile from the
house like it hadn't ever happened.
Today, I was able to reproduce it twice on the same road (with a really large
valley in it, going up the hill both ways, within 500ft from eachother). I
decided to try just moving the petcock back and forth from 'ON' to 'RES' a few
times, and it just started right up after that.
My theory is that the canister or one of the lines to/from it is plugged,
probably the third equalizing one so that its always drawing a vacuum on the
tank, and at high rpms I presume its drawing more vacuum than it can equalize
and therefor starving it for fuel? It normally stutters and acts lean, even
though I checked the screens up in the tank on the petcock inputs, and pulled
and cleaned the carb out (was pretty clean already).
Has anyone seen/had this happen on their bike? It acts a lot like a bike that
someone noted in another thread (can't find it now) that ended up being a fuel
issue but they originally thought it was ignition/electrical related, and they
had replaced the CDI/stator/etc.
Ideas? I'm gonna pull the canister apart and see whats up after I put the kids
to bed, maybe I'll figure out my problem and I'll drop the details here if I do.
Otherwise, I noticed the board is fairly active around 7-8PM EST, maybe someone
knows the answer for me and I'm looking in the wrong spot.
