My stock 98 vmax is running stupid rich and I can not for the life of me find out how to adjust for this. this is a new bike to me. the guy I got it from let it sit with gas in everything for 2 years. I have cleaned the carbs and found that the jets in the holder where both screwed in all the way. this was giving me the very rich setting and popping at 3000RPM. I've tried adjusting the mixture screws but no setting helps. do i need smaller pilot jets?
