DS/FD Meltdown
« on: July 07, 2017, 01:56:37 PM »

(1987 K75C, type code 0564.

[/size]Does anyone know a rebuilder of FD and DS or a source for used parts? My DS rear splines are cooked while the pinion splines on the FD are in poor shape. I am unable to locate a used FD on beemerboneyard or eBay. My local BMW service center does not accept bikes built before 2000 (!).


I spoke to famous FD/DS re-builder, Bruno Sax, who is out of action for a few more months pending recovery from health issues. Bruno said I might get 30,000 km out of a new or rebuilt DS fitted to the existing FD (vs 150,000 km if fitted to new FD splines). Beemershop.com offers their after-market DS for US$349 and that might be worth ruining in 30,000KM but it would be nice to get an affordable FD. Ideas welcome.


The transmission output splines are fine. I have photos of all splines but previous attempts to attach them have resulted in error 500 (unable to do what you want us to do).


Suggestions appreciated.

My new ds was noticeably starting to get chewed up after only 200 miles married to a bad fd spline.  Don't do it.  Get new ds from Ted and send your fd to virginia motorad.  I had mine done there.  Very happy.  Bike shifts are SOOOO much smoother without all the worn part slop in the system.

Thanks mlytle. But I do not see Virginia Motorrad in the Interwebs. Could you provide a contact point?

Photos attached.
