Freestyle Blowsion SS850 topend, anyone running it ?

Been away for a few days didn't see this thread updating. Kawi9: Seadoo 951 pistons WILL NOT WORK in Blowsion sleeves. The ring locator pins will put the ring gap in a port. I use a Cr 500 based piston. Stock length rods are border line rod ratio with a +5 mm Stroker. Blowsion sleeves will work best at no more then +4mm stroke. Good luck but honestly I would think of letting someone with experience building these stock casting 89mm engines serry it up for you. The set up on the engine will make or break it.
