    I put a new motor in and I've run about a tank of gas through it, and I can't get to idle. I was checking it today and there was a little oil around the plug as I shut it off there was a slight bubble coming off 1 of the head studs. So I think maybe it's a airleak that's causing the no idle symptom. It runs good through the rest of the powerband. What do you think?

    Ya I had another motor with airleak symptoms I sprayed with water bottle and the head bolts leaked but that wasn't the problem. Intake had a hairline crack.

    Too lean

    I did change out the head gasket, but that wasn't the problem. I had it jetted too lean.I'm thinking about buying aftermarket carb I've checked out the sha clone, mikuni and the dell orto,I'm kinda partial to mikuni. Anybody have a recommendation?

    the SHA isn't fully adjustable since it has only one jet. get one of the other two.
