| irk, not that hard but need some tools like flywheel puller and rattle gun
simple things like grinding out the weld in the exhaust and matching the maniflod to the gaskets can give you a little but extra but minimal.
carbys can give more power or just tune your current one,
also changing the sprocket setup can change how the bike delivers the power.
otherwise your looking at pistons borework porting cams to get heaps more power |
