Starter turning over too fast means...??

Someone please please please tell me that this is a simple troubleshoot. I had to put in a used starter on O (I don't even wanna talk about the previous one), and I've got a full circuit - but the starter's turning over really, really fast and the engine's not catching. What've I done?

Ok, now I am gonna talk about the previous starter and the one before that - the darned insulated block that goes between the starter casing and the bolt that connects to the starter lead broke. This is the second starter on which I've had that piece break. I know I can be a little hard in my wrenching, although I swear no sledgehammer was involved. Anybody else finding these little things to be fragile?

Sounds like the bendex on the starter isn't extending to get the engine to turn over. Might just need to lube it, but that's just a guess as I haven't been into a starter on these bikes.

lube the bendix with Wd40 on the bench, then jump it with a battery on the bench a few times; When it loosens up, put some white lith grease down there in the bendix;

Its the gear assembly that spins the flywheel.

I think you know the answer to that ha ha.
Have you bench tested the starter to see it in operation?

Yep, I did and it seemed fine. Here's the thing, though - I had the other starter on the bike and then realized that the insulated deal was broken. So, with sleight of hand, I pulled the bad starter off (leaving the left-side cover (as you look at the bike from the front) on the engine block), lost a little oil, and slipped the other starter into place. So the piece that goes between the gears on the starter and the starter gear in the engine is not the one originally associated with this starter. Make sense? I have a feeling I'm gonna have to drain the oil and try this again this evening...

Update: I changed out the starter and put all the original parts back together again. Didn't bench test first (pro'ly shoulda) 'cause I thought perhaps it was just a bad fit previously. Still no go. I have spark at all four plugs and compression (spare-finger-check method) in both cyls. Here's my concern: everything I'm reading suggests that when all else checks out, you're looking at a top-end problem -valve seating, timing... I redid the top end on this engine, and I know the valves are firmly seated (checked via the leak test - tight as a drum), but I'm not so sure about the timing. Non-750 repair manuals suggest that a timing adjustment is "a quick fix," but - as someone else recently posted - seems to me the only way to adjust the timing on our bikes is with <sigh> an engine pull. Is that for real, or am I just missing some easy step somewhere?

Mastertech, my hammer remains within easy reach...
