What's up fellas I just got my motor together on my bike it's a 421 cub and I can't seem to get it tuned to save my life. So 4mil 421 cub with pwk 38mm quadravents stock jetting. Now what the bike does is it won't turn up as if the motor is screaming but it's getting too much air "guess" and it's not very responsive on the throttle and nor is it giving me the power I know it has. It will idle but doesn't sound 100 and yes it's running on both cylinders and I'm running 8" pod filters I need help!!!!
