Engine vibrations, not from mounting
Yesterday I put a new CDI on my bike, one that I found on ebay rocket racing cdi. Worked great, rode it and engine did run a lot smoother and less vibration. Now today, for some reason it's vibrating much worse, and heres the iffy thing. When I pull in the clutch going to a stop, the engine revs up for a second, but does go back to normal idling. What could this be?
