    Help with my 787 rebuild

    I'm currently rebuilding my 1996 xp 800 and the motor has me stumped as I don't know a whole lot about them. The ski had some mods done to it when I purchased it in 2008 and i'm looking to keep it reliable like it has been but maybe some more power. I want this to keep running on pump gas so thats means 93 octane where I live in TN. It was the original motor so i'm starting from a stock internals. What I don't want to do is make a snowball effect where I have to start replacing everything.

    Current mods it has
    - Factory Spec II pipe
    - Water injection
    - Adjustable rev limiter
    - R&D nozzle
    - Impeller
    - Jetted carbs with flame arrestors ( plan to keep stock carbs)


    What crank would y'all run? Pistons? any porting? Different head with domes?

    If you want to keep it reliable ditch that FFP spec 2 and jet the carbs to stock. That pipe loves to eat pistons. Ask me how I know. As for the rebuild once you open it, it's pretty simple....what are you stumped on?
