Yur probably overjetted on the mains, however, turn the air screws to 3.25 and consider 130 mains. Depending on how open yur pipes are now, but many people unknowingly overjet which wastes gas. Remember, yur trying to set yur bike up the way u ride, which aint wide open all the time. Stock RWHP is from 49 to 53HP dependant on the bike. I went to 64.7HP with pipes and airbox elim. Now runnin CR II carbs and am over 70HP / 52.7 torque. Next stspe you can get rid of the airbox but removing the snorkel is a start, with the airbox you are overjetted, wannna bet??????
