Guide to rebuilding starter?
 
I ordered a starter rebuild kit that will be delivered later today. I'm not sure what kind of documentation it comes with, or how self explanatory the process is.. is there anything on the forums or elsewhere that documents the rebuild process? I've done a search, but am coming up empty handed. Aside from draining the oil first, I'm not seeing much info.

Well, got the kit today. Everything went well at first, drained the oil, unbolted the starter and pulled it off without incident. Cleaned it off and disassembled. The first problem was getting the old bearing out, it's in there extremely tight. Unfortunately ended up breaking it when getting it out. No big deal, the kit includes a replacement.

Second problem were the brushes.. two of them did not fit comfortably into the slot/sleeve where the coil spring is. Again, not a big deal, I sanded them down lightly until they fit. After fighting to get all four brushes into place to slide things back into place, I went to go put the other cover on... and it wouldn't fit.

Turns out the bearings provided are ever so slightly too small. The kit actually included two bearings, one that is too big to fit into the cover housing, and fits loosely over the shaft. And another that slides easily into the cover, but doesn't fit the shaft. The original bearing is right in the middle as far as sizing goes..

I'm going to contact the seller on eBay, but even if they ship me the correct bearing I'm without a bike until it arrives.. How can I tell what size bearing this is, and where can I buy something like this locally?

Replying to my reply, because why not?

Got everything back together. Took my dremel to the inside of the end case and shaved about half a millimeter off all around. Bearing fit after that. Put it back on the bike, filled her up with oil and she came to life on the first crank with no effort.

Warned her up for a good ten minutes and shut it down. Waited ten seconds and tried to start back up - this is usually where I end up endlessly cranking until my battery runs down...not this time, started up first crank again!

Finally I went for a ride, couple miles to get things really warned up. Got home, shut down, started right back up first crank! I think I can safely say my hot start problem is completely gone.

My bike won't start with a full charge. Turns over all it wants but no start. Might try to do a starter rebuil instead of ordering a new one. How big of a job was it?

So your engine turns over at stored but won't start... I doubt it's a starter issue. Sounds more like your ignition coils are heading south.
Try the coil relay mod
