Starter just spinning, HELP Please!

[ariel]

Hello to all and anyone who could help. I have a 1986 Yamaha FZX700 Fazer. The bike starts up on the first try most everytime. But after riding for a while and shutting it down, I would try to start it again and all I get is a spinning and whining sound from the starter. It is as if the starter is not engaging somehow. A while after it cools down the bike will start agian. Does anyone have any possible answers. Thanks in advance!

Wild guess time.....


The bendix gear is sticking when the starter is hot. Starter removal and cleaning of the bushings and shaft the starter drive gear run on may help.

A lot of the starters are designed so the bendix shaft shears, if it sticks to the fly wheel, or over torques. If you remove the starter, connect a pair of vice-grips to the bendix gear. Jump the starter with a pair of cables, to get it to activate. The bendix will probably kick out, but not rotate. You should hear the armeture spin. Otherwise, the bendix will kick out, and you'll hear the armeture hum. If that's the case, check to make sure the fly wheel has been ground down, on the side facing the starter. However, you would probably hear grinding not spinning, if that were the problem.
