64-64 600's

another good thing for the 96 is put the 94 head gasket in it. the 96's had a thicker one. no need to compensate the jetting for it, they were too fat anyway. if you have access to a dyno, get it done so you know exactly what rpm to run. they were notorious for being over revved.

If the 96 has the newer motor, I know the xt's did, then 137.5 or 140's depending on the temp, needles in the top groove with one washer under. 55 pilots sounds familiar. Ran two of them this way for years at 8000 and up.

Clutching - 8cr's with 3.6 in each hole. GPG spring or a something similar. Secondary was 43 or 45 with a green at about 70.

As for the 94 - never messed with one of those.
