Another year has passed by, and I wanted to wish all of you a wonderful Christmas and a Happy New Year.

As our old BMWs get older, we spend more time keeping them in tiptop condition. I have explored several upgrades that have proven to me, that some components on our old machines have just reached the end of their life due to wear and design.

I have explored several upgrades that have made sense to me, including; Seibenrock Cylinder upgrade and the Wedgetail ignition replacement. Next will be a Mikuni carburetor upgrade.

The Seibenrock upgrade and the Wedgetail ignition are unique upgrades that have made my old 83 R100 RT run better than a new one.

After fighting with my 40 mm carbs, I have decided they are just worn out. I will be replacing them with a Mikuni carb kit from Rocky Point Cycle. The box annoyingly sits on my dining room table as I work on some problems with my old pickup truck.

I installed a dual cylinder head temperature gauge on my RT. That is what convinced me that the 40 mm carbs need to be replaced. They are a flawed design, in my opinion. I see the other smaller Bing carbs that perform well, but the 40mm don't work well when they are perfect. Even though the bike runs as well as it ever did, I found the CV design too large to work consistently.

My 77 R100 RS is sitting protected in my garage, and my 77 R80 has found a new home in my son Christopher's garage in Lockhart, Texas. I recently had to strip the wiring harness apart and replace much of it due to an electrical fire caused by the switch being left on.

If the motor stops in the wrong position, the coils will overheat and, this time caught fire and burned much of the wiring harness. I have developed a solution putting fuses on the coils and the main power supply from the battery. It's is a hazard for many of the older bikes with points.

In a nutshell, that has been the story in my shop over the last six months.

If you would like to upgrade your Airhead, I would love to have a TechDay event to share what I have learned.
