Starter parts question

Hello all, been a while since I've posted. I had time this week to work on my bike and have finally put it back together (bought a while back as a basket case). I had to clean up the starter internals to get it to turn over for me, and have even had it running (though poorly) for a short time.

My question is what is the sleeve inside the starter around the armature? Mine seemed grooved up inside, like it had been warped and gotten extremely hot at some point. I ask because when I try to jump the starter from a 300cca lawn mower battery, I only get about a minute and a half of cranking time until the battery is dead. I can jump it from a running vehicle and actually pull down the vehicle's charging system (headlights dim really low). Seems like the starter is dragging really bad, or shorting somehow. What is the sleeve, is it supposed to be there, and should I look at buying a new starter instead of rebuilding it?

I think the "sleeve" is probably the field coils. More than likely, the bearings/bushings for the armature shaft are shot allowing the armature to contact the coils, scraping them.

Sounds like that starter is shot, and too expensive to repair. The starter is definitely dragging.

Jumping the bike off a running vehicle can cook the r/r (regulator/rectifier).

Pictures would be awesome.

Without knowing too much about starter, I would say that if the rebuild kit includes the all pieces that are worn out then maybe go that route. If the starter looks like its warped and not really repairable, then maybe just get a new one.

Don't take my word for it. I'm just a foolish newbie.
When in doubt, just know that I am only joking around.

Thanks for the replies. No, I'm not cranking constantly, it's just a summation of total time I get to crank on a single charge.

I can try to yank the starter again to get some pictures of the sleeve in question when I have an opportunity. I didn't realize jumping could hurt the regulator, so I'll stay away from that in the future. The bearing and bushing seemed ok when I was cleaning on the starter, and the brushes still had the majority of their life left, leading me to believe the starter doesn't have much use on it. We'll see how it goes soon. Thanks folks.
