    I don't want to distract from this thread, I think there is some cool information being shared here for the budget minded builder
    hugh, with all due respect i just wanted to throw it out there that my 74 is a 447. i think that some 74's are 256 and some are 447, not for certain. just dont want confusion on the subject.

    yeah, there are a few oddball mismatches mid year in 74.

    I'd just like to apologize coming off like an ass earlier lol.

    I was in a bad mood and I think the heat is getting to me. So again I'm sorry for the dick move back on the other reply.

Not too hard, but a little time consuming.
    does this go for any xs650 motor? having a tough time figuring it out in my brain, but having a problem doing that...i guess you're gaining more length in the cam chain which would make the cam be running behind where it should be? all year cams press off? would like to make a little more compression out of a (mostly) stock motor.
