Might as well start by stopping. Going to replace the front disc brakes that is. |

As everyone knows, 2020 was not a good year for traveling of any kind. Especially international travel. I had a couple things planned for the year which had to be canceled. In early 2020 I started doing some major work on my motorcycle. It kept me busy and was fun and interesting. I thought I would provide some pictures of the work I did. I've done work on the bike over the years, but this was so much work and occupied so much of this year I thought I'd post this. If you know anything about BMW Airheads, you'll understand what I did by the pictures. If you don't, then you probably could care less about this page of my website anyway...

Might as well start by stopping. Going to replace the front disc brakes that is. |
Easy enough to replace the front brake pads, but might as well do it all. |
Also did a complete rebuild of the front brake calipers. |
Replaced stock discs with EBC floating rotors. Really nice. |
Added Denali yellow daytime running lights (DRLs) for visibility. |
Determined low compression, later found the valves were not seating properly. Time for a top-end job... |
Head off, top of piston exposed. Not to be confused with top dead center (TDC). |
Cylinders will get new stainless steel pushrod tubes and pushrod tube seals. |
There's part of the problem. The valves were not seating properly. |
While I'm waiting, replaced the oil pressure switch. |
Sent heads, cylinders, and pistons in to BeemerShop. New springs, valves, rings, stainless pushrod tubes, etc. and a nice vapor blasting treatment. Ain't they pretty? |
Some assembly required. Piston and cylinder back on the bike. |
Head back on the bike. Need to adjust the valves. Remember - torque, torque, torque, very important. |
Organization, a key to rebuilding the carbs. All the new parts placed in a muffin tin, the old parts put into a matching empty muffin tin. |
It's the little things. Like which cable is choke and which is throttle. Don't ask... |
Replacing diaphragm, jet needle, and spring. Make sure everything aligns and the jet needle is on the right notch (the 3rd notch for me). |
I'm using a main jet of 145 and idle jet of 45. Lots of fun getting the new o-rings on. |
Enricher gets new gasket and o-ring. A real Airhead knows it's not really a choke. |
Ready to start putting back together with all new o-rings, gaskets, floats, float needle, jets, springs, diaphragms, everything. |
Both carbs ready to go back on the bike. |
Took the old petcocks zu (off) and put new petcocks auf (on). A bit of fuel petcock humor. |
New Thunderchild dioide board. Determined a couple diodes were bad, but I sure didn't know it by riding the bike. |
New brushes installed. This job should have been easy. Yup, should have been. |
The famous Airhead Bean Can, remanufactured by Euro MotoElectrics (EME). There are several options to replace this, I chose to stick with the Bean Can. |
Went with a Denso starter. There are several (cheaper) options to replace the starter, I chose this option. |
New Bosch ignition coil. |
New voltage regulator. I'm going to miss the pretty blue color under the tank. |
New Thunderchild Ignition Control Module. This thing does so much related to the starting and running of the bike. |
New light relay, why not? |
Now simply called the yellow relay, it's for the starter, horn and various switches. |
New 'choke' cable that goes to the splitter. My 544mm cable was not available, so I bought the 671mm cable for the '77-'84 RS. No problem. |
The 'choke' cable splitter and the left/right cables were still available. |
As smooth as I thought the clutch pull was, the new clutch cable made it so much nicer. Apparently, I was overdue for a new clutch cable. |
I liked the front Denali yellow DRL lights so much, I bought the matching rear Denali red parking/brake lights. I already had replaced the stock tail/brake light with LED years ago. |
Nice clean install, lots of bright light. I additionally bought a flashing unit so the Denali brake lights flash. ATTENTION GRABBER!!!!! |
New Michelin Pilot Activ tires for front and rear. I really like these on this bike. |
Decided to buy a No-mar tire changer. Got a great deal. |
No problem removing and reinstalling tires when you have the right tools. Also got a really nice Marc Parnes wheel balancer (on the right) to complete the job. |
Finally, all back together and running phenomenal. Time for some riding. Here's where you would normally go to the next set of pictures, my next trip, but one more picture left. |
A little late, but still oh, so nice... Now that all this *fun* work was done, I buy a Harbor Freight motorcycle lift. But, there's always more *fun* to come... |
