    785 FUJI black or blue?

    I have a black engine. Trying to figure what piston I need to buy. What are the differences? '97 Pro

    My understanding is the stock 785 piston is no longer available from Polaris. However, a standard 750 piston will fit the cylinder perfectly.

    KJ

    the pro 785 piston is not available anymore from polaris but some dealers still have them on the self if you search around ,you can go with 750 pistons but you will need to change all 3 because they are lighter

    Because I can get 3 750 pistons for $200 or 1 785 Wiseco for $120. #2 and #3 are in great shape. Would rather no replace them if i dont have to.
