Them damn jap bikes...now when my Buell starts doin' that I figure it's maybe bad gas or something...(not fouled plugs) 'specially if i've been to taco BEll.



Hook up an air hose with about 3000 psi and blow the jets right out of the carbz. You should have EFI anyway, so get with it.

If the thing has 16 K on it, it's probably getting to be about time for a major tuneup. It could be a little bit of this, a little bit of that, all adding up to something noticeable.

Ask yourself these questions and then follow the path that the answers give you.



If you are running out of power between 6 & 7K in low gear, then chances are you don't have a fuel problem as the engine uses very little fuel between idle and 7K in first. If the engine appears to be losing power in one of the higher gears, then it could be a fuel problem or a spark problem. Hard to tell the difference unless you're familiar with symptoms of this type. Easiest fix for the latter symptom would be to replace the plugs. If that doesn't solve the issue, then you can pretty much count on the fact that you have a fuel delivery problem.



Any garbage that's found its way into the float bowls will pretty much clog the idle system first, as that's the one that's being used the most, so I'm not big on that theory that some posters suggested that the problem lies with the main jets. I'm going with plugs, but whatever it is, let us know. It's always fun to see if Troubleshooting-By-Mail works.

I wish I had a set up that would produce 3000 psi.

Thanks for everyone's help. Yes, I realize I shouldn't have ridden it this long etc... It's a problem that's been easy to ride around on the street. I plan on doing a major tune up to it which will include new chain and sprockets, plugs, pipe, jet kit, fork fluid replaced (possibly revalvled), head bearings, and valves. Should be ready for a track day in August. I'll let everyone know how it works out. I'll start by cleaning the carbs out first and the plugs.

It's about about 8k. I'll start with plugs.

I'd just trade it for a new bike.
