Re: Which model had this gear cover

I found that my R50's breather plate surface on the cover had been machined, I had to remove the circlip from the spring to get the plate to contact the rubbing surface. Works fine that way and later bikes did not even use the circlip. Just a b!tch to install with the engine in the bike! Dave Hi Da...

Re: Which model had this gear cover

Mal, The one with the tachometer drive cover missing is the upgraded timing gear cover. It was upgraded June of 1967 and the service bulletin is available in our library at https://vintagebmw.org/library_data/250.pdf . So, if your motorcycle is above the serial numbers listed in the service bulleti...

Re: Which model had this gear cover

Well another question re the front gear cover. How high should the breather plate rubbing surface sit proud of the machined surface which is outside the wear path? Thank you in advance for your help people. Regards Mal Jan from Salis has told me .2mm, which rather surprised me, as it is not much. B...

Which model had this gear cover

I bought a secondhand gear cover out of Germany. Attached is a photo of the 2nd hand gear cover in the front and the original gear cover from my bike. Someone has made an adapter plate to convert the older cover so it will accommodate the later model generator. Which model does the front cover come ...

Re: Retouch or repaint?

Well at least that has narrowed it down.

We are standing in the foyer of the hospital waiting to find out what happened to our friend.

Re: Retouch or repaint?

What a bit of bad luck. Given the symptoms, unfortunately it is not likely to be a five minute fix. If you leave the bike in neutral, can you turn the engine over using the front crankshaft bolt? That would tell you if the engine is seized up. If the engine turns over, then I guess it's probably goi...

Re: Shift fork size

Mal, Great question. My guess is that the slider is about 6mm. I don’t have one to check. It’s really the “twist” of the fork in the slider that seems to matter. There is a transmission article in the Winter 2021 Issue (I know who wrote it ;) ). I suggest changing over to the eccentric shift fork b...

Re: How much of the restoration will you do or did

@mal : did you have any bad experiences with work that Salis did for you or other people ? I am in Australia, so have no experience with work from Salis. I do get parts from there amongst other sources. Jan at Salis has been very helpful and I think he would always do quality work. I have had my fr...

Re: How much of the restoration will you do or did

I did a total restoration .the bike wasn’t really pretty anymore when I bought it. The engine was done by Salis, the striping by : oldtimer linierung in Wiesbaden And the assembling I did myself. All together a nice result I think . BEFORE : F83D659D-8AA0-4EC1-A0DE-0E4E7C0B4C09.jpeg AFTER : E30F9B9...
