Points Backing Plate /2

Post by pshosticka »

Setting the static timing on a /2 seems to me would be so much easier if the 2 screws holding the plate to the body and behind the advancer were hex head so allowing for access from the side. Could then be done in one simple step accurately. Does anyone know of a source? What is the screw size and thread? Thanks in advance.

I ordered a pack of M4 x .7mm x 6mm length SS low profile socket head screws from McMaster-Carr. I used them for multiple locations on the points plate. $6.30 for 25. I use a L shaped 2.5 mm hex wrench that I shortened by a bit to fit under the advance. Much easier to deal with than slotted screws.

A quick check on ebay shows some from china for cheap.

Thanks for the good info. I'll get some from McMaster- Carr in the mail today. One would think that those smart engineers at BMW had thought of it.

Low profile socket screws were not common 60 years ago, much less SS. Easy to source and buy today.

In addition to the points plate, these low head screws can be used on the spring clips that hold the coil in place. Makes then a lot easier to get to.

Once on McMaster-Carr I found they have M4X.7 6mm in both low profile socket head as well as hex head. I ordered both and ended up using the hex. So easy to make the adjustment with the advancer and thus the point cam in place. A 7mm combo wrench reaches and easy to snug. Also a shortened allen wrench works well. Not to disparage German engineering in any way. I have and have had British bikes and cars of the same vintage so well know of what I speak. Lots of other applications as well. It is a good trick and should be included in future restoration guides.
