    slt 750 piston questions

    My piston in the back has a small dimple in the top of it. Being as small as this dimple is should I replace this piston? If not how long will it last? They are fairly new pistons. My third piston has a bad burn spot through it as seen in the picture the ski had the priginal fuel system setup moving to the complete fuel upgrade with this new build. Can i reuse the top head gasket with adding "copper spray"? Also how do you change the crank seals and oil seals? I'm going to be using premix with a three outlet fuel pump kit anything else I need to change while the motor is out? Thanks for your help. Click image for larger version.

    Run the piston.

    Read this for tips/suggestions.

    What you need to know about Polaris 650 750 780 785's


    And get a manual for the rebuild. It has proper torque specs, and sequences for you to follow.

    What about the head gaskets with that copper spray is it safe to use?
