That's what I run too, Josh....with a 20" Holeshot XC. I wouldn't recommend it for a stock machine though. Just sounds to me like you need more power. A decent piston, cam, exhaust, intake etc and you should be making enough power to blow through the stock gearing pretty good. Wiseco has an 11:1 piston now, a web .390 would work pretty decent but I think Jeff is running something else that he likes even better and that's saying something, he's a big ole boy, lol! I just don't care for the Hotcams, the power isn't that great and the bike constantly sounds like it's going to grenade under you. Noisy mofo's they are!
