BMW R12 Differential

Hello. What size or designation does the differential bearing have? I am sending a picture in the attachment.

Does anyone have a differential repair manual?


Thanks everyone for the advice.

BMW R12 number on frame

Hi, Can someone measure the size of the numbers on the BMW R12 frame for me? (VIN code). How big are the numbers and where is the number located? Thanks

Re: BMR R12 performance

Thanks for the advice, you were right it was bad timing. I adjusted the timing and the engine runs like clockwork. Otherwise, you have very nice machines, thumbs up :)

BMR R12 performance

Hello, friends. I have a BMW R12 and it has no power while driving. He doesn't go as briskly behind the throttle and into revs. What can it be and what to look at? thank you for all the advice.
