my 03' WR is finally running strong, and i switched the starter clutch. the starter button never really worked, and after some pretty gnarly uphill rides, i really wish i had a magic button.
i'm gonna check all connections tomorrow, but i was wondering if there were any guides out there on how to repair a startor motor, preferably with pictures.

To service an electric motor, common jobs are:
Clean internals
Replace brushes
Cut commutor
Test on a Growler

The last two have to be done at an eletric motor shop (unless you have a metal lathe, then you can cut the commutor)

sounds pretty straight forward. how do i know when to replace brushes? i've never seen the inside of a starter before.

One more tip. Mark the orientation of the housing pieces before you take the motor apart. The position of the magnets is important when you reassemble it.
