    Smokeysevin's STX 900 conversion buildup (not a duplicate )

    I posted this in the kawi section but I figured everyone here might have some better insight.

    I have some friends with a 2001 stx 900 with a locked up motor that they may be willing to part with on the cheap so I figured I would start looking for some project ideas. I really want to build a monster 15f motor and drop it in, I'm looking for something in the neighborhood of 200 horsepower and preferably N/A, im figuring that a mild overbore with an offset ground crank and zx cams should put me near that with some head work and a header, I want this to be a test bed for everything that I have been wondering what if about and be dead reliable. so this is what I'm thinking

    buy the ski and strip it and sell all the 900 parts on the cheap
    pull everything and true the hull and clean everything up on the inside
    get a hold of a 12f or 15f motor and a zx12 or zx14 motor and swap as many parts over as I can
    do the head work and get a header
    overbore and maybe stroker
    make the entire thing show quality


    if there is anything else on here that yall think I should do or any problems post them up I have about a month before I get the hull


    If anyone knows anything about the N/A 4 stroke kawasaki motors please post it up because thats the part that I need the most information about

    I should be getting the 900 tomorrow for some reason the Kawasaki dealers are always closed on mondays... we'll see I'll have pictures up ASAP I still need to figure out where I can pick up a motor and an efi fuel tank being that I wont need the oil tank anymore and I would like some extra go juice.

    Yeah, I have one of the kawasaki dealers looking for wrecked skis and wrecked zx12rs for me but they haven't turned anything up, I also need to find a pump because im pretty sure the one in there is trashed. DOES ANYONE KNOW A PLACE THAT HAS USED KAWASAKI MOTORS FOR CHEAP?

    Sorry man I saw it first lol I got out of class this morning and was like CRAP I was looking forwards to getting that for $30 lol Small world, now if you see a motor HANDS OFF lol the guy shipped it like ten minutes after I payed I was impressed. I should be getting a call from a lady with a 15f that has a "low hour blown motor" lol im not sure what that means the inside looks like but im going to try and pick it up on the cheap.
