I was hoping for some help with engine mods, do ceramic bearings add rpm? Modified sleeve/cylinder? Porting, polishing, tuned pipe vs. Jett or Nelson mufflers, etc. I know I can bolt on more HP with a Jett or other high performance engine, but, were locked in to the super tiger 45's. I had hoped somebody had done some of these things before. I would appreciate any info! Thanks, Oh yeah, I live more than 500 miles away from most of you so come on share some of that knowledge.
