Just fitted the 170 bore kit with stage 2 cam, pulled the carby down to change the jetting only to find it already had a 112 main jet in it anyway it had a 38 pilot jet, so i put a 120 main and a 42 pilot got it all together got it started and it ran as rich as buggery, so i went back to what was in it and ran a lot better but it is still rich,took it for a ride and it is a heap better than standard but after i came back from my ride i pulled the plug out and it is still black, any ideas??? So now the carby is the same as the bike came with but when you ride it it feals great.
