Have to rock bike to get starter to work 5 Months ago  
My friend has a 2004 Road Star tells me today he has to rock the bike in gear to get the starter to work sometimes. Any ideas what is going on? I told him I would do some research so here I am. Thaks.

can't know for sure, but usually that indicates a bad solenoid. Either corrosion limiting it's ability to return to a normal position, or dirt/corrosion at the gear mesh point.

Does he have proper voltage at the start when this happens? If so there is an issue with the starter. have him take the back cover off the starter and clean things up. and see if this helps.

That isn't the way our starter works. ours is a constant mesh type starter and does not have a gear that throws out to mesh like you are talking about.

Sounds like a faulty or dirty commutator or brushes to me.

My thoughts also that is where my suggestion above comes from. The bumping turns/moves the starter to a different spot.

Could be the decompression solenoid. Bumping the motor in gear moves it off compression, giving the starter a running chance at turning the motor over.

Thanks Dave, another lesson learned. Question: does that mean the starter drive gear is always freewheeling when the engine is running?

Yep, That is also why you will occasionally hear the starter whining noise when you shut the engine off.

What is a constant mesh type starter and how does it work? Thank you.
