Hi there,
I've got a 98 P model for Racing purpose only.
It was used and in a bad shape, so Im rebuild and cleaning everything.
The carbs are my main problem.
Thanks to the workshop-manual I could identify the wrong main jets and worn floate valves and swap them.
Also the sparkplugs, sparkcables and fuelpumpe are replaced now.
But from time to time the carbs are shaking/twitching. (Don't know how to express it correctly in english^^)
For better understanding, here is a short clip from my carbs.

carbs - zx7r

Could someone give me an advise what I should do next?
Cheers

Is it doing it when the bike is just idling? Or if you were to raise the revs to 3000 rpm does it do it then? To me, it looks like a slight mis-fire and the carbs, being mounted on rubber, move because of the misfire. Does the engine move or jerk as well?
