Anybody ! Starting system checks out perfect electrically hot or cold. Can hear solenoid banging in but no start. Engine does not turn over. Apparently, jack shaft does not move far enough to energize starter motor coil. This problem occurs after parking the fully warmed up bike for more than 5 min. It can take an hour (usually more) to cool off enough to start. The bike will start with a push. I replaced the jack shaft last September and the hot start problem went away for 2500 miles. But it is back this spring. Fuel system is okay too. Runs great. Anyone out there run across this problem???
