      I was under the impression that 3-disc provided better performance, and maybe more longevity for the clutch.

      Interesting.  David, any idea why most people I’ve seen run a 2-disk in our class? The guy I talked to said the 3disk was better at both performance and longevity. As you stated.

      2-disk was designed for the lower horsepower Yamaha Can. The Yamaha Pipe has more horsepower, obviously. My guess as to why they run the 2-disc is because it is more readily available, or they use it when switching to Can. I would contact your engine builder to get their advice. My guess is horsepower related.

      The 2-disk is OK for a jr canned Yamaha. For a Yamaha senior with a pipe, I’d go with a 3-disk, six spring. I know that’s more rotating mass, but I believe that it’s easier to adjust, will hold that adjustment and there will be fewer head aches.
