Trusting your gut

One of the initial problems I had with this bike was the alternator rotor.  The key was missing, and the holes were so wallowed out that the screws attaching it to the starter clutch wouldn't stay tight.  As a result, the hole for the pin which was supposed to lock everything up nice and snug was also worn out, and way out of round.  I never found anyone who could fix it and I couldn't find a replacement.  (My son found one and gave it to me.)
Anyway, when I put this all back in, I tried using the original pin (rhymes with original sin) even though I could tell it was worn.  Not nearly as bad as the hole it was supposed to fit but it was worn and I knew it.

When we originally tried last year to start her (I'm starting to lean towards "Sadie" as a name) the sound of the engine turning over sounded differently as the alternator screws worked their way loose.  I thought I had a hint of that the other day when I tried to restart her.
I knew I was going to have to pull that alternator to be sure it wasn't coming apart again...I didn't want to go backwards but I didn't want to screw up that new rotor either.
Sure enough, things were starting to get loose.  Not bad, not yet, but it wouldn't have taken a whole lot more.
I called around to some local places to see if maybe they'd have at least the pin but no one had it.  I decided to try the place where I ordered the retaining plate for the starter sprocket.
They seemed to have it, so I ordered some new screws and the plate that goes between the starter clutch and the rotor that holds all the little goodies inside and the little spring caps for the clutch because one of them seemed to want to hang up and let the roller kind of flop at times, and I'm hopeful that the order confirmation e-mail I got means that they really did have the parts.  Now I just have to sit and wait by the mail box every day till they come.
It's a real downer to have gotten so close only to have to wait on parts again but... it is what it is. 
I feel good that I had enough sense to check it out rather than to just push blindly forward and screw something up again.
By the way...here is a link to the dealer that I've had some luck with as far as finding parts:
