    what is the top speed for a 1990 pahzer 2. i can only get it up to 72 at about 7000rpm. but if i take off the clutch and put on a dummy clutch it goes up to 10,000rpm. do i need to rebuild the secondary?

    70-75 mph is about all those sleds had. You might see 80 mph if you were on bare ice or a road, but thats about it.
    Those Phazers were only intended to spin about 7,000 rpm and I can tell you for a fact that making it turn 10,000 rpm is going to make that motor blow up. It was never designed for those kinds of rpms.

    if your clutch is set right your sled will do 85 normal day. no matter what terrain. my old 90 always did. and if you got the right conditions id get 95 outa her. loved that sled. nothing like a phazer!!!

    LMFAO!!!!!! Bull sh*t you got 85 let alone 95 out of it. The best I've ever gotten was 83.9 on the gun. That was on ice, with an AAEN pipe, Clutched at 7800m with some very minor porting, and vmax 600 carbs. So Don't get to carried away with your BS Speedo speeds! Another CYI!
