This is a "Low Post" Polaris primary which was a dealer take off from a 440 cc trail sled. Dealer installed electric start clutch with ring gear on original sled. I purchased the "take off" not knowing it was a low post configuration for a low hp engine. I only put a couple hundred miles on it trying to tune it for a 100+ hp sled.............good luck. It has been sitting in my garage since 1995 & needs to go. It is the standard 30mm 1:10 taper and uses 1 3/8" wide belts. There is a 569 etched below the date of mfg on the clutch cover, visible in the pic. Would fit many sleds in the 50-60 hp range, but I'm clueless what weights and springs you would use.
