My Franken Beemer is down with a rear leaky master

most surches I conducted to how has not produced a kit to rebuild it

Another question is recently I picked up a late model final drive for Disc with no drum brake ability ( installed just before the leak
so does the early Non Drum brake final Have the same guts (gears)as the early drum brake case

If so I'd like just to install the guts (gears) into my empty final case I saved from my 1977 33/11

I can't see why they'd be different, but I'd go double check via the maxbmw fiche to be sure.
The biggest job you'll have is re-shimming the pinion to the crown. Many shy away from this task, so if you have a go, a few words and pictures would be fantastic.

Motobins sell rear M/C kits for £17 or £25 depending on age of bike. Their export service seems to work well

Well I don't know if the parts will fit as I checked Chas and although the drawing show no difference the parts number from the 1977 33/11 does not match the later part number from say the 1975 or match the later 1982

3 different years 3 different bikes 2 with a brake drum 1 with a disc and none of the number match

I think that '77 was the earliest year of the rear disc brake models, you could always ping 'Bins an email to ask........

Think I'll just go back to drums and look for the right rear drive

Personally, I really like the feel of drum rear brakes. Not the thing for the track, or even a hack or Goldwing on a steep 3000 ft. descent, but, for most riding, I like them better.

The best thing I can say is, as I rebuilt or modified! I found truth in my work, and nothing but trouble about how delivered
Meaning some parts came so used (woreout)and other parts needed rebuilding in deep levels (insterments and Pods)

New stuff into old stuff, a Fellow can build the bike easly enough if the arse bearing is not too tight and one not to scared to try... I was beatin when I could not afford the cost to keep orginal

Some prices too high but the Answer was better and cost less but made more work
When I got my other bike the stress on my BMW became not so much in the desire to prove the work on ATE or Brembo systems

Because after all I could buy the kit and do the work and find I'd really need a NEW MASTER CYLINDER because it was after rebuilding my under tank and the BMW kit failed to fix to find the Honda piston parts fit and worked......

replaceing my Mags going back to wire wheels

Any one want to buy my mags the rear wheel has the bolt on spline

also how many have done rebuilding the master whats the success or method OR am I taking a change like the under tank rebuild?

as I found BMW send the same piston size and no others are around if you know the bore of the master let me know maybe I'll be doin the Honda experamnt again........................

I have the rear wheel set back to wires and drum, I just might keep the front disc's
