    Rights are nearly impossible to find as it is the one side that always falls off. A new one from BMW is $115.00.

    I'm pretty sure side covers didn't show up until '72. So in your case you're not missing a right side, you have a spare left side.

    Friends, I have an 81' R100 with a 99k+ miles on the OE Drum brake 37/11 final drive. It has alot of drive lash and the diff is shot. Will a 32/11 from a 74 R90/6 bolt on without drama?

    let me know asap as it's on ebay and I don't want to lose it.

    37/11? I thought that was specific to R80 STs and G/Ss. Both of these had 3 lug hubs. As far as I know the R100s had 4 lug hubs. Double check which you have and don't buy the other one.

    I was mistaken, in low light, a german 2 looks like a 7, so...

    I actually have a 32/11 and the housing is ribbed, not a smooth casting like I've seen.

    I think the diffs might be OK what do you lot think?

    They'll interchange. I might be interested in getting your old one from you - send me a PM if interested.

    Mark, there were 37/11 twin shock final drives as well.

    You can use any 70-84 twin shock rear drive as long as it has the brake pivot hole in it. Not all 81-84 rear drives had it.

    No, just for the early BMW bags that had the metal latches.

    does anyone know the part number exchange, Valeo copy starters for R80G/S?

    this appear to be an Asian made nine tooth permanent magnet starter that fits, BMW R series Airhead with 9-Tooth, Replaces Valeo D6RA7, D6RA15, 12 41 9 062 425

    these are probably made for a popular Japanese auto with several applications. starter mfg generally will not make new starters unless there are lots of sales to justify tooling.
