Dropped the needles the two notches and set timing, it was not advanced enough. Down the road, bottom and mid range great, top end I thing rich. But a real problem is getting it to shift. Without my modifications trans it seems a little snug. Down shifting isn't a problem but up shifting is a" when it wants to" situation. It had been rebuilt by PO. Engine a little noisier then I like when hot, I think it's the short pistons, not really a knock, again with velocity stacks everything is exaggerated. Might be the gas tank jumping around, I want to run it a bit and see where it is rubbing before I finish paint it. Seat height is 27 inches without 1 inch foam. Handling is GREAT! Doesn't want to fall over at slow speeds and follows a line in the small curves of my neighborhood. Hope I didn't use up all my luck on this build! LOL
