    1990 js550

    Greetings...Just scored a 1990 550 that is very clean and low hours on built motor with shaved head, 5 gal. tank, and some other goodies. I am going to ride it this weekend in Yuma. More pix to follow. Should be a smoker!

    ive seen this ski somewhere before.... hmmm. I would dump that stock breadbox exhaust for a half pipe, throw a top loader intake and stainless impeller pitch of your choice, bored nozzle and quick steer plate and that thing will rip!

    Head is milled. Carb is 44. Does not need exhaust. Stainless prop, top loader, ride plate, Guy that built this has 30+ years exp. and says current set-up is fastest. It does go.
