Tuning bits

[OB_Yngve]

Anyone who gets hold of a dyno printout of a Hayabusa with modifications please send it to me. I plan on fitting the Wiseco 1429 big bore , port my head ( yeah wise cracks, make your joke now ) and install an acropovic race system on mine. I will be putting minedyno readout out on a homepage but it will ot happen until the end of August ( due to money shortage )
I have seen some dyno tests with slip on cans and they gave a few horspower ( up 4-6 ) but I want the full monty. Not just a slip on.

My Uncle Frank is also Developing a big piston kit for the Hayabusa. I believe somebody form Puerto Rico sent him the motor. I will keep you posted what h.p. improvements he gets. He have been making pistons kits for motorcycles for over ten years. I have a 95 harley that he built that have 110 rwhp, nothing like my hayabusa! but its one of the fastest H.D. in Chicago area.

Hey Robert, What is the deck heigth above the pistons? (stock) .040? .060? or less?

And how thick are the cylinders in the Block?

I been thinking about ordering a extra block from Suz.
