i put in my new z-start clutch last weekend. we rode about thirty five miles. i spent alot of time trying to get it set up right. it was easy to get used to and i had a blast. as the ride went on it seemed to slip alot. when i got back i found a lot of mud had gotten on top of the tranny and had kept the actuating arm from moving like it should. i cleaned it up but it still seems to slip more than it should (or did). i know my answer is to tear it down and check everything but i was wondering if other owners have had similar problems.
