ive just come in from trying to get my bike jetted, first off its a 97 200 with fmf pipe and silencer, open airbox, boyseen power reeds, premeium gas mixed at 40:1 yamalube, 2r, i pulled the carb that was supposed to be jetted when i bought the bike, "never belive anyone" inside i found 158main, 45 pilot, so i followed advice here and dropped to a 152, 42, setup, it was 65degrees here and i think my elevation is about 2,200ft but in mid clip position it was running way lean, so dropped the clip and tryed again still lean, so pulled the carb back off and changed to 155, 45, in mid clip and airscrew at 1 1/2 turns out, much better but still seems to be a bit lean, how can this be? everything ive read says this should be way rich ,it started to rain before i could try moving the clip down to try to richen things up a bit, not sure what to do at this point, i could always go back to the 158, 45, setup but on cold start it was a bear, easy to foul a plug but once warm ran ok, any positive feedback on my delima would help, im starting to pull my hair out, and i dont have a much to spare, HELP ?
