Is this problem more likely to be in the starter or just a stuck starter button. Before i start taking things a part it would be nice to know where i'm most likley to find the problem.

starter button

Let's see, power goes from battery to starter solenoid, then to contact in starter switch assembly that is grounded out by pin on button going through brass bracket to complete circuit and actuate solenoid, sending power to starter motor.

So it's probably a short in the switch assembly. Check for the bakelite contact board being pushed out of place or bare wire touching the case. Watch out for tiny spring in button, it'll try to get away.

I've been fighting this for awhile. I ended up splicing in a 1-1/2" piece of wire (soldered to back of contact) to replace fraying wire inside case. Plus some shrink tube. The original wire was too short, pulling the contact board out of place just enough to ground the contact. Routing the new wire more into the case, then out to handlebars seemed to fix this. I guess we'll see

Hope this helps --Lee

Disconnect the yellow/red wire from the solenoid and see if the starter still engages when you turn the key on.
If not, it's probably in the switch itself like Lee says.....if it does, it's probably a stuck solenoid.

If solenoid was stuck closed wouldn't starter run even with ignition off?
