Clutching is the key to performance.
Have you ever been sitting in the staging area at a race?
Thinking if I only had a few more RPMs engagement I would get a better hole shot, well we have a fix for that.
We have put a lot of thought into the new NEXT LEVEL adjustable primary cover. Its new shape helps reduce wind drag which causes HP losses. The cast bronze center bushing is longer then the stock bushing to give better support to the movable sheave cover reducing wear which causes poor clutch performance. It has an easy to adjust, patented multi position center hub that allows you to quickly increase the spring pre-load adjustment from stock to .060 without the hassle of removing the primary cover. In testing we have found with certain springs engagement was raised by 500 RPMs or more. Includes tool to adjust settings, shims, and dry graphite lubricant.
*THIS COVER ONLY WORKS FOR THE STANDARD JR PRIMARY CLUTCH, THE OVERDRIVE COVER IS COMING SOON.*
