My Shee won'rev at all, idle is fine but as soon i hit the throttle the bike wants to stall, sounds like a cutoff, compression if perfect on both cylinders, maybe a bad coil ????
exactly what I was thinkingstrokeittwice443 said:check the T.O.R.S. switch at the parking brake lever. if the parking brake lock is not making a good contact it will not rev. this is the most common area that will trigger the override to cut the engine back to an idle. they become loose and will lose contact.
