Bump.
Found this thread while searching for info on the three OEM head gasket thickness options: 0.10, 0.40, and 1.00. Why is one recommended over the other?
For my particular situation, the bike has a Pro Circuit Platinum 2 pipe, the Pro Circuit recommended jetting, Larry's compression release head (thanks, Larry), and is stock otherwise. Riding is a purely recreational mix of trails and forest roads although I like to be on the pipe.
