Re: Piston Skirt mod for improved performance?
I was reading that the top end should suffer but I didn't notice this. Then again I don't usually let my engine hit the high revs for long. Being able to power up hills is far more valuable to me. On Main hill I ride It gets up at maybe 25kmh with the mod at WOT and only 20 or a bit less without the engine will never max out RPM wise on these hills.
