Starter Clutch Removal/Replace?

Hi, everybody! Thanks in advance for responses.
I have a 1986 Rebel CMX250. I need to replace the starter clutch, and I want to do it myself. My manual (Clymer) does not seem to have anything on the starter clutch. But I can't find any good diagrams or instructions on how to do this. I've done a bit of research and the most I can find is that I need a flywheel puller, and someone to hold the brake while I remove the bolt that holds the starter chain sprocket in place.
Any suggestions on how I can get more info? Maybe the name of a good shop manual?

Seriously, The starter will start to slip.
If the starter spins but the engine doesn't.
It starts with a slip every once in a while, particularly in colder weather.
Usually starter clutches don't fail catastrophically. They tend to slowly degrade, gradually getting worse until they don't catch more than they do.

Keep in mind the starter clutch is not part of the starter motor like in an automobile.
The starter motor drives a sprocket which drives a chain. The driven sprocket is behind the flywheel and is attached to the starter clutch.

I would suggest putting your bike info in your signature.
The 250 starter clutch is very easy to get to and rebuild. It is on the left side outside of the crankcase and quite robust, not a known weak point.

The 450 on the other hand has in internally in the crankcase and requires splitting the crankcase to access the starter clutch.
The symptoms are the same, a slow degradation.

This thread is a little old but it touches on exactly my problem. So hold on to your butts. I could use some input.

I brought my 86 cmx250 to a shop to get the carb cleaned because the screws holding the carburetor together are apparently made of aluminium so my philips head destroyed them, requiring help from a professional. Once they got it back together, the guy said it runs great...when you push start it. So they say the starter clutch needs to be replaced. I find this believable as when I hit the starter before i brought it in it would make this horrible screaming, metal grinding kind of sound.

Here is the kicker, they have had this bike for 2 MONTHS!!!

I won't go into the detail but it has been an uphill battle to get to this point and they are in the process now of searching for the appropriate part. (I think this is week 4 of their search)

From what I'm reading this looks like something I could manage with a strap wrench and a few other tools. I am just unfamiliar with the exact parts that need to be replaced. That pdf manual sounds like it might be my key to getting my bike back if Rebelrider86 would be so kind.

You probably can. I tore my bike and engine down to every last screw and spring, and rebuilt it. In one day, on a few concrete paver tiles in my front yard. No manual. The schematic provided by this forum was helpful.

Don't be afraid to jump into this bike. It's simple and hard to screw up. Once you do it you realize "Hell, all that apprehension over nothing! That was way easier than I thought!" Psyching yourself out is the biggest hurdle. You gotta be a real special kind of stupid to wind up in any serious trouble.

Thanks flitecontrol! I would take you up on that if you happen by. Getting the bike out of their shop is the first step. Does anyone have a link to part/parts that would be needed? These mechanics are under the impression that the parts were discontinued and are hard to find...
