I am thinking about adding the Wiseco 10.5:1 standard bore piston with the stage 1 HotCams cam on my XR650L. I am wondering if anyone has this setup, and how well it works with the stock starter and no decomp?

This has been talked about many times, use the search.

I run this setup with an FCR, porting, and yosh exhaust. The engine makes more power but in a different place. I lost the low end torque (might be the porting with open exhaust system), but gained tons of mid and top end power. For supermoto this is desirable, for tight woods riding maybe not.

It will run hotter at slow speeds, some people have added oil coolers. I will soon.
