I believe this emoticon perfectly demonstrates how I feel.
It was not a final drive failure. It was a damaged pivot pin paralever. I'm not quite sure what that is because all I heard was "NOT FINAL DRIVE NOT FINAL DRIVE" but I'll find out more when I pick up the bike.
The oil sight glass had started to leak so they're replacing that and it was out of synch at idle so they're doing a tune up.
I plan to learn how to work on this bike myself.
What do you y'all think the first maintenance thing I should do is?
Thanks for your input folks - this experience has been harrowing and educational.
