so I seen a video on youtube with a crf 250 that the kick start locks up on it. one of my sons friends has the same prob. not all the time but ever now and again it will lock up and you cant kick it. if you put it in gear and rock it then back to neural it will work. but if you run a recluse clutch? any one know what this is? seems to me like a bad gear or something . but im sure its more then 2 bikes that this has happened to. any thoughts?
