Andy, what would be your suggestion to get some more ponies out of her without having to rebuild every couple track days? Maybe somewhere in the mid to high 60's then? Do I dare say 300 kit Shocked If I get someone to do some porting, will that severely increase the rebuilding process? What would I actually have to rebuild? Are we just talking pistons and rings? I don't think that that would be such a big deal. I have my other MC21 as my streetbike which puts out a solid 60hp as well. I'm just sick of having those 600's creep away from me down the straights, though it's not too big of a deal once we get to the braking zones Very Happy . What would be the best way to shave some lbs of her? Not really sure where I can get anymore weight savings besides putting in a lithium battery. I already have some billet calipers getting mounting next week.
