[QUOTE="kawaguy, post: 959713, member: 58277"] make sure you got the right size piston, it could be just the slightest undersize for the size of your barrel, but this problem sounds like a powervalve prob, make sure you put it back together properly and that you adjusted the powervalve lever, when adjusting it make sure the pv is fully closed and flush inside your exhaust ports and barrell before your set it right.
