Right now i have a stock stroke shee with VF 2 reeds, 2-1 intake with a 33pwk. Stock bore, fmf knarly pipes with power core 2 silencers.+4 timing. I mainly ride on trails and a little hill climbs. This setup is ok but the topend has cleared 160 hours+ and i inspected the pistions and they are pretty bad with a little play. Just looking for a little more power. What else can i do that wont hurt the pocket but add a little more hp? any suggestions welcome
