    Yamaha 63m 1100 riva engine big bore ported billet head vibratech/fluidampr aluminum

    I just took this in on trade for some other parts I had and I do not have any use for it. i took the head off to see what it looked like on the inside...here is what I can tell from the best of what I remember when this was in its hayday.....
    1171 cc
    63M(1100) bottom end ported cases by riva and stock 1100/1200 crank 68mm stroke
    Vibratech/Fluidamper coupler part # 716650
    Riva light weight aluminum flywheel
    Riva Billet Reed Spacer
    63M(1100)fully ported cylinders by RIVA bore is 85.5mm
    65U(1200) pistons 1.5mm oversize
    Riva Billet Head cover with gridle
    Riva Billet 84mm Domes modified to 86.00 mm bore

    this engine has been sitting around for years.It turns over fine. I would have to say maybe 10 years or so it was oiled up very good but should be gone through. Cylinders look good and might just need a hone. Pistons look like they are Pro-X and I would replace them. I would also split the bottom end and have the crank rebuilt...just to be safe...from what I remember this engine on a stock pipe that was extrude honed and with 46mm red tops and a mod prop did somewhere in the mid to upper 60's? It was the fastest raider around in the NJ area... This guy also had nitrous on the same ski and I think it was doing about 71-72 in 1996...

    sold as-is where is

    please contact me for shipping

    the big question????? how much do you guys think it is worth? I can rebuild the entire engine if you like or hone the cylinders also...I know I am not on the yamaha side but check with the polaris guys and/or some of the moderators they will tell you that i am ok and I have been doing this for almost 18 years now and have worked on MANY yamahas...

    i am not interested in parting it out as of right now.

    Thanks
    Jay
