rktek sent me a 36 helix. works good. I had gill vents on the side, now i have a mod rod vent on top of the hood, I also have vents by the speedometer. the motor mounts you have some choices. infront of the motor beside the oil pump is a mount. you can buy one of these from arctic cat and put it on the other side of the oil pump. I also have a torque stop on top of the pull start/recoil housing. I made mine but some guys around here are buying them from a guy named brent linderman. there are some pictures on snowest but i don't have any.
