This afternoon pulled the bike out to warm up and prepped for a morning ride we're going on tomorrow. 1st kick with the choke on she fires right up and i let it run a little before pushing the choke back in...few seconds later dies. 2nd attempt with choke on again starts right up..push choke back in and give it some small throttle chops, no high revs, dies again. Now with the choke out go to kick and when its at TDC I cannot kick it. If I put a little weight on it it will slowly slide then I can kick but as soon as it gets to TDC it stops. What the eff! I pulled out the spark plug and I can kick it smoothly....My guess is a stuck or bent intake valve? Help!
