    '93 SL750 Piston

    Anyone know where I can find the best price on a Piston for a 1993 SL750? I only paid $500 for my Polaris with trailer and I just figured out why.. A nice big crack in the #3 piston. (The guy said it ran fine and he had it going over 40 mph last time he rode). I'm just afraid I'll dump another $100 into it and it still won't run right.

    You might want to check the crank index. Do a search for "crank index".

    If it was hydro-locked, that could crack the piston, AND torque the crank shaft out of index.
