If its a drag port its not going to have much low end. Mayve you need more clutch to keep the revs up. What jetting are you at now?
loco-alittle insight on why people may doubt your tuning abilities. Its either you, some guy they dont know at all, or jim, a guy who they have actually talked to and who built them a very fast engine that they are more than happy with. My engine from him is rediculously powerful and easy to tune, so i have no reason to believe jim would make a slow engine. When I hear some guy I dont know at all saying theyre no good, I have no reason to believe him becuase my experience has been totaly different. But what would I know im just an idiot with pussy ported passion jugs...
