My bike is running rich, as it splutters a lot on WOT. I have ran it with air box lid removed and it runs a lot better. Main jet is a 147, can anyone recommend what size main jet to change to? exhaust is a CRD open pipe. Is there a point changing pilot jet as it runs ok on low revs.
I agree its strange, was running ok before but recently not good. Needle already moved one notch but no noticeable difference. Worth getting any other sizes as well?
As well as Brian's recommendation i would be checking over the float too.. Have you accidently adjusted the float height ? Is the float valve sealing properly ? ( Does petrol leak for the float bowl if you leave the petrol tap on), has the float sprung a leak ?

Bike runs perfectly witout the air box cover so I guess its not electric. Tried my spare carb and problem is the same, also have tried disconnecting the breather hoses and it still splutters. It feels like its hitting an early rev limited with the side cover on.
