hi there,

Is there are standeard setting for the piolet jet screws that control the low runnign of my gsxr? Recently stripped the carbs to clean out a sticking float and while being distracted by the missus in the kitchen started to undo the screw for the jet on either cylinder 2 or 3 instead of the screw that holds the float bowl on :oops: i tryed to guesstimate where it was and screwed it back in but my memory isn't to sharp. since i got it all back together it nedd the throttle pinning with my finger on the starter for about 5 secs before it picks up, and on the road splutters and bangs untill it hits 6500-7000rpm when it smooths out and runs faultlessly. Is there a way to set the pilot jets up or at least a base setting i can start from??

Thanks for reading the post and thanks in advance for any replies

Standard is 1 3/4 turns out.
Seems that might not be your only problem. My understanding is that that the moment you twist the throttle even a tiny bit you are no longer using the idle mixture as you would have moved to the main jet fuel supply :?:

thanks for the setting. i just can't see what else it would be, it was running fine except a float occassionally flooding a cylinder??

Badly set/dodgy float hights are supposed to mess up the fuelling too, it is the only thing I have not messed with in my carbs as they are running well for now and I don't know much about setting them properly anyway. :|
