Starter Question

[Bikeman]

It appears as if the plunger of the starter is activating for a second or two while driving, maybe once or twice a week. It sounds like a buzz or similar to the sound of the ARB compressor that is in my Nissan. The buzz is coming from the lower left area by the dead pedal area. I assume it is coming from the starter.

I ordered contacts and a plunger from CDan today.

Questions Are:
How is the plunger getting power at will if I am not deliberately using the start position?
Are there just electrical contacts that feel like jumping themselves?
Will the rebuild kit fix this issue? I have no other starting or cranking issues. The starter is a Denso Reman. I don't know when is was replaced by PO.

The starter rebuild will fix this issue. My LC shop owner friend explained it to me a few years ago, but I forgot the reason he gave me. How many miles do you have?

If the plunger truly released after starting the engine, then I fail to see how it would re-engage unless you had a serious short in the starter circuit. If you think it's the starter, then don't drive it until you fix it, or be prepared to replace a whole lot more than the starter...

Are you certain it's the starter that's making this noise?

I'm with Tom. Never heard of an 80 starter engaging itself and this would be unrelated to the starter contacts/plunger. Unless the plunger spring is broken, but again I've never heard of that either. I think you're barking up the wrong tree.
