After completing this work, most of the disassembly down to the frame is complete as I also removed the rear sub-frame and muffler that is attached to it.
Rear Drive, Swing Arm & Rear Monoshock
Rear Sub-Frame Removed
Muffler Removed
Down To The Air Box, Transmission, Engine and Frame
All I have left to do is remove the air box, transmission and the engine from the frame.
You can read about how I do this work and watch a short YouTube video summarizing the work here.

Love following along to these builds. Quick question – what is your cleaning process for the aluminum parts (rear drive shown here)? It looks great and I’m struggling to get my R90 to not look 80yrs old…
Hi Stephen,

I hope this helps.

Ah very good! Thanks!
Hi Brook.
When removing my ’83 G/S gearbox, I always loosen the four bolts that connect the drive shaft to the gearbox first. Only then do I remove the rear wheel. This allows me to use the rear brake to lock up the drive shaft/gearbox.
I also find this works better during the reinstallation.
Cheers
Marcel,
Yes, that technique works well for me too. That said, I wanted to see if I just put the bike in 1st gear it would provide enough resistance to remove the drive shaft bolts. It turns out that technique works as well.
Best.
Brook.
