ZX9r running problems at low revs
ch1ef - 16/2/07 at 11:57 AM

When driving my zx9r between 1500rpm and 3000ish rpm the cars stutters alot and misses a bit. oviously this makes it hard to pull away with the car!

the engine is "ZX9R 'E' with TTS dynojet kit"

Im guessing it got the wrong amount of fuel going to the car?
Ive never fiddled with carbs etc before so is there any easy things to fiddle with or is it best to get it onto a rolling road and fine tuned? if so any places near bristol I can take the car?

or any other idea's?

thank you all!

hi mate

under your carbs is the mixture screws these control 1-3000rpm

get a little electrical screwdriver flat head

mark the top with a line

then each screw maye be up inside a little metal tunnel

engine off gently screw all 4 in till there pinched up remember how many turns each one was out with your mark on your screwdriver

then screw each one out 2 turns that is a base setting try that

easy stuff done in the garage
