This is the original transmission from my 1978 R80/7.
When restoring the bike, I installed another transmission and had this one serviced by Steve Prokop in Dundee, Oregon. Steve is a well-known BMW specialist.
Filled it with oil and set it on the shelf as a spare. Its been sitting there 5 years now, so I guess the one in my bike is good to go.
Service cost me $400, plus I figure the "core" is worth $175.
There's no cracks or damage to it.
I am near Salem and could deliver to the rally, or could be picked up at my place, 11 miles away.
If I was to ship this, I'd only charge actual shipping cost. I have a FEDEX commercial account so get pretty good rates from them.
