    Engine removal

    Well the last time I had my jetski out I busted another piston and there are pieces of piston still left in the bottom on the case, so that means I need to remove the engine and most likely split the case. There a set-by-set guide on engine removal for the SL750?

    I'm 99% sure i broke the piston because the clearance was off, I used a standard bore piston on a bored cylinder (didn't know it was bored). Will I do any damage by running a standard bore cylinder with 2 bored cylinders?

    and on the bore issue! it's done all the time! compression ratio's should all be close however! Z

    I'd buy the Polaris service manual, which is more detailed than most aftermarket manuals and net supplied directions. The service manual will also have much better specs and useful information for later down the road (carb settings, specs, timing charts etc.)
    I think you'll find it the best money you ever spent. You would have verified cylinder measurements and learned to properly check ring gap etc. In other words, you will be taught to check and verify each step in the rebuilding process before assembly errors are made.
    Buy the Polaris service manual, they are on e-bay all the time.
    Check with Randy, he'll probably have one or two as well.

    I actually already have the Polaris manual. Didn't even think about looking in there.
