Kinda studders when i go to rev it up from idle. Is it the valve clearance, jetting, or a cam off a link on the chain, (i just put on a new cam chain)

You best make sure you have it timed right with the cams. If your for sure its timed right, I would suggest raising the needle clip.

I agree... Does it run fine on top?
