1983 BMW R100RS Remove Carburetors & Air Box

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.

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.

1983 BMW R100RS Remove the Front End

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:

  • Handlebar controls,
  • Handlebar,
  • Instruments & bracket
  • Steering damper,
  • Front fender,
  • Front wheel,
  • front fender brace,
  • Front forks
  • Steering stem & fork top plate

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

1983 BMW R100RS Remove Brake System

I removed the twin front disk brake system and the rear single disk brake system. The rear brake pedal assembly had a kludge repair to fix the wobbling brake lever. And, the rust was so bad on the rear master cylinder linkage that I couldn’t remove the rear brake pedal and had to remove the master cylinder and rear brake pedal together.

You can see how I did this work here:

I shot some short videos of how all the brake system components are connected together.

Here is what the bike looks like now. I will remove the disk rotors after I remove the wheels and tires.

1983 BMW R100RS Remove Electrical System

After I removed the fairing and rear fender assembly, I removed the electrical system including the main and sub wiring harnesses and the electrical components attached to the frame.

As I did this work, I put together a video tour of the electrical system.
