I have priced things out, and the Athena kit is a much better option as it comes with a brand new head, piston, ring, gaskets, and powervalve assembly. The kit comes with everything I need for the top end. So in the end this is cheaper. I am sure that the Eric Gorr option will give more power but I am only a novice rider, so I will focus more on suspension and stuff like that. I will keep you guys updated and hopefully have pictures of the bike up on Saturday. This will be my first rebuild of a bottom end, and I am rebuilding the crank myself, so that on its own should be interesting. I am more than open to tips, suggestions and comments
