I don't know that much about this particular bike, but it could be any number of things, all of which are going to cost a little bit. Could be a seized top end (piston, hone cylinder, several small parts/gaskets $150-250?). Or, could be a piece from a broken clutch basket ($200-300?) that jammed in the kickstart gears. Maybe a seized bottom end or tranny? Either of which would be $500 or so. Just rough estimates on prices here. Heck, if you're near KC, bring her over and we'll tear it down and see what's up! :)
