@Joe-Rocket just found this for you:It's always fun going faster!
Yeah that looks pretty low, probably a drag bike and not a circuit lover. What i can’t see is how the exhaust ties in to run the turbofan ? Tesla’s going to come out with a bike that will eliminate all that hardware anyway ... the new name for gas bikes will be petro-sarous-wrecksOk, what’s wrong with that picture?

Find the mistake...
YES you can rebore the cylinders, NO you wont ruin them, there are many firms who re-nicasil cylinders in the UK. All motocross bikes have relied on this for years as have all the airheads that needed new pistons.Over size boring isn't an option, the barrels are Nicasil lined. That means that any attempt to over size will just ruin the barrels.
As for a supercharger, don't know if that's been done. A turbo would be easier....
Can I just ask why you feel the engine is under powered?
If it's the slow throttle response and lumpy running at slower speeds I'd suggest a Booster Plug.
