I would like all the specifics if you can. I have a 1990 indy 650 that i would like to do this to. has DG pipes on it already.jesse500 said:Bore the cylinders to use 750 pistons, race port & polish, tripple Deckker pipes, clutch kit, re-gear it, re-jet.
That will make more difference then you could amagine. I had a 1989 Polaris Indy 650 tripple with all that, sled felt like i put a turbo on it. I have all the specifics if you would like to know. PM me.
Sell those DG pipes and buy deckker, i have dyno sheets proving Decker makes 4.9 hp more than the next closest competitor (crankshop).treeclmb1 said:If i bored to use 750 pistons would my DG pipes still be tuned right on my 650?
