I'm resurrecting a 1982 R100 and have it running very rough. The previous owner may have removed the electronic distributor and re-installed it improperly. What is the procedure for syncing it with the crankshaft

Bean can installation

The bean can has a coupling at the end which slots into the end of the cam. Either it is in the slot or it is not. I MAY be wrong but if the coupling is improperly set into the end of the cam, the bean can itself will not fit flush on its two mounting points.
I do not believe there is an "up" or "down" on the bean can. It can only fit on the end of the cam within the limits of its mounts. Twisting the can on the mounts changes the timing. Perhaps this is off? You can check with a timing light in the hole by the oil filler.
The slot fits the coupling, if it DID seat on the mounts with the coupling not in the slot, then all you have to do is remove the can, line up the coupling on the end with the slot in the cam and reinstall it.

Does this make sense? I am relying on my poor memory for this information. St.

bean can resolved

Thanks all for the informed replies. I took the chance of removing the can and discovered that the coupling (slots and tabs) is off-set from the diameter of the circle. So it can only go in one way and not 180 degrees out. The bike is driveable but runs very rough. When the weather warms up a bit. I'll ride it to my nearest knowledgeable BMW mechanic (100 miles). Thanks again for the replies.
