The bike starts great all the time when you can kick it. However, sometimes it gets into a state to where you can't kick the bike past half way down. I weigh 155 and I have to get on a stand, put it at half way and just leave my weight on it bouncing a little before it will make past. Seems if I do this a couple of times all the way down, it will eventually correct itself. Anybody had this problem. Funny thing too, if I cut the bike off and then start it back up, the kick stroke goes through fine and smooth. Just sometimes after the bike has been sitting you just can't kick it all the way through. Any ideas??
