1983 BMW R100RS/RT Routing Main Wiring Harness

I show how I route the main wiring harness after I installed the headlight shell.  Previously I replaced the main harness with one from Euro MotoElectrics.

Here is the document showing the details and a short video.

I completed installation of the fork and seat locks. I show the assembly of the seat latch mechanism and installation and also made a short video showing how I do the work.

1983 BMW R100RS Install Sub-Frame, Gazi Shocks and Wheels

I completed installing the rear end of the motorcycle. The fenders and rear lights will come in another post. You can read about how I did that work in these chapters of the “Assembly From The Frame Up” document:

It’s beginning to look like a motorcycle again 🙂

 

1983 BMW R100RS/RT Assembly From The Frame Up Page

I put together a page showing the order in which I am assembling the bike on this project. I will add to it as I go. In most of this document I link to other pages I posted, but for some work that is not particularly detailed, I show how to do the work in the Assembly page.

There is also a companion document that shows how I disassembled the bike.

I also have documented the project work on a Project Index page that includes a list of every document I published for this project organized by parts fiche major component number.

Here is a link to the YouTube videos I’ve posted about this project on my channel.

Lastly, there is a complete archive of all the pictures on Flickr.

 

1983 BMW R100RS Install Swing Arm And Rear Drive

Previously, I replaced the swing arm bearings and you can read about how I did that here:

Now I install the swing arm in the frame and then install the rear drive on the end of the drive shaft side of the swing arm. I show how I align the swing arm in the frame to reduce stress on the drive shaft when I install it. The rear drive mounts easily to the flange on the right side of the swing arm with four 12-sided nuts.

Here is a link to the procedure:

And here is a video summarizing how I did the work.

I had the swing arm powder coated and cleaned up and I refinished the rear drive that had been sprayed black with rattle can paint.
