2 stroke Ski Stock now allows Superjets to use 760 cylinders and Kawasakis to use SXi Pro cylinders, Superjets can use aftermarket sleeves to get to 850, Ski Stock can add ballast weight, SX-R and pre ’08 Superjets can use a second set of sponsons, and select Juniors can move up to Novice and Expert classifications with IJSBA approval. Kanamori was one of the first who used twin sponsons on a Ski.
