The goods - The CRF V6 clutch is a lightweight machined aluminum flywheel is nicely knurled on the outer edge so the starting wheel can grab it and a collet is included to mate up to to the taper in the back of the unit. Six pins stick out of the flywheel to seperate the shoes and to serve as a guide to the shoe retaining plate. The clutchnut is unique in that it is threaded both inside and out. This is done so a treaded washer can sinch down on a spring in the middle that holds the shoe tetaining plate in place. What's this all about? The V6 clutch is adjustable, by using the included pin tool, you can tighten or loosen the retaining washer to alter clutch engagement. Cool hugh> With the six blue composite clutch shoes, certain and consistent clutch engagement is the name of the game here, this clutch is high tech.
The works - Because I had just tested OFNA's Ultra LX Competition buggy in the last issue, and it was ready to go, I installed the CRF V6 on the Force engine. I set-up the clutch for quick engagement, by not tightening it too much. I took the buggy out for a quick spin. I was very impressed by the quick, smooth engagement of the clutch, over fifteen minutes of consistent running, reacted the same as it did from the first time I hit the throttle. I hit the workbench for a quick tune, a half turn tighter on the spring. Back outside, the engine RPM's raised a little more and the clutch engagement was snappy, really good for coming out of corners hard. After thirty minutes of strait running the clutch hard throught the track, I was happy that its performance was very consistent. Great concept and better performance sum up the CRF clutch system.
