Tusk Competition Clutch Kit with Heavy Duty Springs
Jonpaul in NM
It works in a pinch
I worked to get me through a race but that was all. Faded fast when abused but got the job done. Started to bark at the end held.

Nihilo Concepts Power Valve Blade
Nick in MD
Well worth the money
Seems to be a lot stronger then the stock power valve that only lasted 12hrs. Time will tell but I was actually able to get the 6mm wrench under the membrane unlike the stock one.

Tusk Top End Gasket Kit
PRESTON in IL
Great kit and complete kit for the price!
Contains everything for the top end replacement but the copper washers for the head studs. I wish they would include them and charge 3 more bucks. Great kit for the price. I would purchase again without hesitation.
