Curious as to what i should do for tuning it. you can see the stuff i have done in my signiture. It had 380s in it when i got it and that caused a hole to start in one of the pistons and burn down on the exhaust side so i threw 420s in i had laying around. now it seems i have an air leak and it doenst want to come off the powerband. and ideas? going riding this weekend. anything helps!
