Pip, Sorry man just fuck'n with you. Noth'n personal. You can't make the hole bigger and mean it's gonna make more HP.Your gonna need to alter stroke as well ; via rod, head. Increased compression is what your looking for.As you make it wider you have to make it shorter and breathe better to match. This isn't the best bike out their for trying make it's engine over perform it will never catch up with a pure liter engine. Very few professional privateer 's even attempted to use this bike in compitition. I believe Jake could've won the last two formula x titles if he would've used his head more but without the backing he recieved from the factory he would of been average at best. The bikes main attributes are it's chasis, handleing and feel, thats what makes it a favorable option for the steet. If your crazy about producing a streetbike with outrageous hp this probably is the prefered package. You'll loose realiability and basiclly be turning it into a timebomb. Yes my bike is fast and I'm not crazy or jacked enough to think it needs to go any harder beyond basic modification. It's how you ride not what you ride, crazy only gets you killed. Hope you aceive the results your looking for. Peace-Out, T. PS Sorry gentlemen, but yes, I am an asshole.

yeah, im pretty much dead set on droppin a turbo on it and reworking the engine and shit, no matter what i need to fuck with it, its a tired bike in stock form, and the new one is ugly as sin, thanks, i did like to see him out there on the 5er last season though
