rebuilding a ktm 125sx

Anything I should do while im done there? How could I make it have more spunk with out boring it. I will have no bearings and crank in it, and gaskets of corse, maybe a way to lighten the flywheel? Porting and polish? head mods? I will run a wise co. prolite piston. its a winter project so just give me tips, I might even throw the motor into a go kart! :busted: Thanks

You could mill the head. What year? I assume you have the 2k1 flywheel and that is the lightest flywheel.
