someone did a good tutorial on syncing carbs a while ago on here.
look in the carb section for it bro.

Before commencing synch work, would suggest (1)assuring no air leaks and (2)determining which if any individual cylinder is responsible for the ultra-high idle. Synching is usually one of the last tune-up procedures after everything else (ignition, spark, timing, compression, valve lash, any necessary internal carb adjustments and cleaning, etc.) is correct.

thanks. when i get off work tomorrow, or maybe saturday, ill do a spark plug check, ill start with #3, because thats where i did the work. i dont know if i asked this, but what if i have the jet needle set at the wrong height, will that cause this problem?

Doubtful, as jet needle has negligible effect at idle speed which is based almost entirely on the pilot circuit. Jet needle becomes effective as the throttle opens.

where did you get that kit kano? how much did it cost?

conventional, i think. they are the standard mikuni carbs that came on it

hey patton,
well i tried to crank it up, wouldnt stay running. im in the process of tracking a short, no power anywhere. i have gone over the carb intake boots, and checked to make sure there are no cracks, everything looks good, if i could have kept it going i could have done the spark plug check. ill try that during the week.

The leaks of most concern are in connections between carbs and engine (not in the carb intake boots between the carbs and airbox). Recall the spray test earlier mentioned (requires a running engine).

actually i meant the other side, where you are talking about. not sure the names of everything, the book i ordered is not here yet. i removed the airbox already.

Hello, have you check if your slides are sticking or seated properly? Even a tiny increase in the slide opening causes the engine to race.
