Re: Smoke from intakes and Crazy Throttle
I wonder if the cam chain skipped a couple of teeth, when you revved the throttle. I can't explain smoke out of the intakes otherwise, barring valve failure, which doesn't seem to be the case. It might also explain your other problems. You should check the operation of the throttle linkage first though, as Bill suggested. You can see the pulley the throttle cables connect to, at the left side, between the frame and the tank, so you should be able to visually determine whether it's getting stuck or not.
