I added a page, 61 BMW R75/5 Removing the Wire Harness & Electrics, showing how I removed the wiring harness and electrics. I took detailed pictures of the wiring layout, labeled all the ends and made some sketches so when I reassembly the wiring, it should be a lot easier. Here are some of the pictures.

I just posted a new web page on rebuilding and refinishing the fork tubes. You can see this entry on the right hand column and can access it by clicking the 31 BMW R75/5 Fork Rebuild link.
I’m labeling the web pages for this project with the number BMW uses to identify major sub-systems of the R75/5 so you can easily correlate procedures with parts. You can see the numbers on Hucky’s /5 parts page.
Here are some before and after pictures.

Over the Christmas holiday, I restored the Bing carburetors. A restoration is a bit more work than a rebuild since the goal is to restore the finish to factory new condition as well as replace worn parts and all the O-rings and gaskets. Much of the time invested is in cleaning and polishing all the parts. You can access the web page about this using the this link:
which is also on the list of pages to the right. I’m using BMW parts subsystem numbers for the rebuild blogs so you can correlate the procedures with the parts. You can see the numbers on Hucky’s R75/5 parts ordering page.
Here are some before and after pictures.

Before starting a project and spending money, I try to take an inventory of the bike’s condition and develop a plan and budget. Usually, for a bike this old, I can plan on replacing everything that’s rubber, all the control cables, and renew all the filters. Since my wife has owned this bike since 1978 when I bought it for her as a wedding present, I have a pretty good idea of how it has been maintained and any major problems. Overall, the bike is in good condition for its 40-year age and 97,500 miles.
I took a number of pictures to document the “before” condition and to help with an initial parts list for the project. I also removed the front fender, gas tank and seat to get a better look at the frame and chrome to better see the condition.
This is the high-level work plan I came up with.
Here’s some of the “before” pictures.

Here is the link to the web page that I will use for documenting this rebuild. It’s a two owner (my wife being the second), 97,500 mile, 40 year old bike that’s been stored in a friend’s barn for the past six years. I’ll post some blogs on the project as I go.
I’ll also keep a photo scrap book here –> Project Progress Photos
