I got the engine out of the frame yesterday so I’m finished with disassembly (small cheer can be heard).
I wrote a document that covers the complete disassembly procedure in the order I did the work.
This may be helpful to you if you are doing a frame off rebuild/restore, or you need to know how to remove various subsystems. The bike, with the exception of the body work, fits into a reasonably small pile of boxes … sort of a boxed, boxer if you will :-).
A Boxed “Boxer” 🙂
Onward. But first I’m giving “Grover”, the 1973 R75/5 some well deserved attention.
I’ve finished removing more on the bike and have posted documents about how I did the work here.
I also made a short video showing how to remove the top end.

At this point, disassembly is almost done, and the real work begins; repair, rebuild and refinishing all the components of the bike.
Earlier, when I first got the bike, I rebuilt the carburetors and removed the “Pulse Air” system from the air box. You can read about how I did that here.
The following includes similar information to what’s in the documents above, but here I’ve simplified it to just removing these components as part of the complete disassembly of the bike. You can read about how to do that here.

I’ve completed the disassembly of the rear end of this bike. Previously I removed the rear fender, tail light and turn signal assemblies. You can read about that work here:
Here is where I started.
Front End Removed & Ready To Start On The Rear End
And here is what the bike looks like now.

Next up is removing the transmission, clutch throw-out arm and rod assembly and the foot shifter mechanism.
I finished removing the front end from the bike last week. I wrote up two articles showing how I do this work that you can find here:
Before doing this work, I also removed the center stand as I put the bike on my portable motorcycle lift to make it easier to remove the wheels and forks.
In summary, these articles show how to remove:
Instruments & bracket
front fender brace,
Steering stem & fork top plate
I started here:

and ended up here.

Next on the work list is removing the rear wheel, rear drive, swing arm, rear sub-frame and seat lock mechanism.
