Xr650L need power.

I have decided to get a XRL. The first thing I am doing ASAP is desmog, air, pipe, jet, Heavier springs front and back.

What about adding a standard bore HC piston and hotter cams, how much will that give me. Anyone add a HC piston w/o boring it out?

Are there any DYNO charts out there of an uncorcked XR?

A HC piston, hotcam, race pipe and tidied ports should give you around 45RWHP.

Not sure about the HP, but yes, stock bore with higher compression and a good cam, it will be a whole new bike with a lot more power.
