Hello, I need a little help from somebody who should know. I lost the engine to frame bolt on my k 100 /1983. Try to find it in motobins, no luck, try in OEM parts page, cant see it. The only way is to find it in some workshops, but dimension looks strange, somewhere between 7 and 8 mm.
Anybody knows correct dimension?

Normal 1,5 mm pitch threads.

If you lost the one on the left side, it could be that a shims between the engine and frame also is missing.

Rubber bushings is only used on fairing models.

According to parts manual it should be shims present (if needed),
factory workshop manual says no shims on your model.

I would trust the factory manual....but if it is a distance present I would have mounted a shim, to avoid stress on the frame.

As matter of fact I put the full rt fairing from another bike which normally goes on frame with rubber dampers on the front part of frame. Its probably better but dont believe I can put rubber on the old k 100 frame

Then you must drill bigger holes in the mounting lugs, not something you do in the backyard.

BMW recommend to not fit a fairing to the solid mounted frame.
But on the other hand, it`s plenty who have done this, without any problem.

Keep an eye on the welds between the lugs and the tubes now and then.

Thanks Inge, the fairing was really good, complete and I didnt resist. Mounted it properly, the only difference are that bushings. Its looks ok, no vibrations. The only thing I forgot was the contra nur on the left lug which lost somewhere.
