Ken, don't mean to hijack the thread but have a question relating to clutch for you. When I had the motor replaced in my '07 at 80k I had them replace clutch plates as they were worn. Dealer suggested the Screamin' Eagle plate set which I got. Did not know at the time but it also replaces ALL plates including the spacer ring. I noticed that with this clutch there is precious little 'friction zone.' It engages very quickly and I even stalled the motor a couple times at first. Also have spun the rear wheel a couple times taking off in uphill incline and giving a little too much power. Now I'm getting used to the clutch and liking it but is the elimination of the spacer ring what causes this difference?

I don't know. The Barnett and Energy One kits have an extra plate in them, and the increased grab surface probably grabs a little differently than stock... and more securely. I really don't remember if the Energy One changed my friction zone or not. They have different approaches... The Energy One kit has all of its own plates, while the Barnett kit continues to use the inner spacer ring. I have no idea why.
I don't know if the SE kit contains an extra plate, or whether the 9 plates are just thicker than stock. I haven't really looked at it.
This really doesn't answer your question, does it?
