Hello, Sue, and welcome to the coolest R65 forum on the planet.
No brag, just fact.
-John WayneI've used Ohio-based Re-Psycle
http://re-psycle.com/ for a number of gently used R65 parts; seat locks, fuel caps, handlebar switch... they can help you with a simple 800 telephone call. Ask for Mark or Marco. Actually, they're
both named Mark but they say it keeps from confusing customers.

Chicago BMW
http://chicagobmwmotorcycle.com/store/ offers new BMW parts at 20% off the website price. I like to call and confirm parts are
in-stock. 800 number there, too.
Others will chime in soon. Post a photo of your
hot bike when you get a chance.
