  1. Oldie....650sx w/stuck cylynders....HELP!!

    I have a 89 650sx that I'm redoing and I can't get the cylinders off!! I've let them soak, tried a little smacking on the sides, heat, and now I just made a jig that has a 1/2 plate bolted to the cylinders and 2 6 ton jacks (1 on each side) that sit on the mounting plate, that's only starting to bend (with heat!)
    Anyone got any suggestions?

    Thanks ahead of time........

I rebuilt carbs and new fuel filter and fuel pump seems good, good pulse to fuel pump, new plugs, new Boysen dual stage reeds, 3 piston skirts on reed side look good. Compression 120 on all. Checked timing at 15btdc, good, Suppose to be A RA1100T but not sure if it's a 95 engine or had been changed. Any help would be greatly appreciated? I give it
  3. 87 440?

    Howdy, I was just wondering what would be the compression on a 440 with a milled of .100? And how much can you mill a 87 650sx head?

  5. 1976 400 hard to start after running

    So my 400 will start no problems and run great! After about 20 mins of riding and then letting the ski sit for 20-30 will not start again. I have been reading that the mikuni 38 bn
    after riding ski will dump all the fuel into motor and the only way to start is open throttle all the way to allow more air into motor.. I have found this to be true but only 50% of the time . Does anyone
    know how i can fix this problem.
