My new Steel version is on the left, the aluminum OEM on the right.
The rear swing arm assembly I got on Ebay said that it had the pivot bolts in it. Except 1 (of the 4) was missing. So back to ebay and found 2 bolts listed for an R1150/R1100 rear swing arm. Got em for $20 (inc shipping) and thought all was happy happy. Well nooooooo. The 1100 has a different thread than the 1150 and these turned out to be 1100 bolts. Same in every other way. Go to the Web and find that I can just order the one I need from Max BMW for $28. Except you can't just order one, you need to order two! So with tax and shipping it turns into ~$80. I have a lathe and some steel (the OEM are actually hard anodized aluminum) why not make one? So I did, and spent a day to make a $28 part. Of course the other justification for this is that it would have taken 10 days, at least, to get it from Max, as I'm sure they didn't have it in stock. So I feel a little better, and it's always fun making stuff too. And broaching them for the 12mm Hex Key was included.

Transmission mounted to the engine with an almost viable adaptor plate. the modified flywheel with clutch mounted all seem to fit. I have to make a few adjustments and I can machine the final piece out of aluminum. I'm also proud of the new engine stand I made. Sometimes it's the simpler things....

MDF. This is to make sure I have all the hole locations correct and that the width is right so that the input spline of the transmission has enough engagement with the clutch . If this is correct then the finial piece will be milled from aluminum. That is a BMW Clutch mounted to a heavily modified Smart Flywheel. I'll try to post images and a description of the process of mounting the clutch pack when I can find the images I took during the process and when I get a bit more sleep (see previous post).
