Starter clutch...couple Q's

First off, are the rollers, plungers and springs supposed to just fall out when you pull off the clutch? Because mine did. One of the springs was a little messed up, the others looked alright.
Also, there was a copper spacer between the clutch and starter gear that was pretty deformed and a bit burned up from the looks of it. I'm guessing that also had something to do with it slipping?
Anyway, I'm gonna go ahead and order new springs and a new spacer off bikebandit.com so I can get this thing back together.

That's not what my starter clutch or flywheel looks like at all.

Z1 doesn't show anything related to the starter clutch at all.
Does anyone know if that spacer is copper, or is it bronze? I think I can probably get a copper or bronze washer and make it work without too much difficulty.
Or is it even that important of a part?

Whoops.
I was thinking "Clutch"...my bad.Must have been too early,lol.
And the spacer that you're referring to,is listed as a "Spacer" only.

It looks just like a bronze thrust washer, except it seems to have some "dimples" in it almost like it was ball milled. The OD is almost exactly 1 11/16".

I meant how important is it to the functionality of the starter clutch? It looks like the only friction surface between the starter sprocket and the starter clutch. I hope it's OK to reuse the old one (albeit cleaned up) for now.

....I meant how important is it to the functionality of the starter clutch? ...
It is not at all important to the functionality of the starter clutch. When the starter clutch is activated by the starter, the starter clutch (and rotor), washer, and starter sprocket all spin at the same rate, in the same direction.
However, it is critical to the functionality of the running engine, once the starter clutch is done with its work. The washer keeps the starter sprocket away from the rotor, allowing them to spin separately once the engine is running. Because at this point, the starter clutch is in motion with the rotor, and the starter sprocket stands still.
EDIT/UPDATE: I see the pic you just posted, and yeah, I'd use that washer. It looks funny, but should still be fine.
