BMW   

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.

top

BMW - bmw2020_002.jpg13K

Also did a complete rebuild of the front brake calipers.

top

BMW - bmw2020_003.jpg13K

Replaced stock discs with EBC floating rotors. Really nice.

top

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...

top

BMW - bmw2020_006.jpg13K

Head off, top of piston exposed. Not to be confused with top dead center (TDC).

top

Cylinders will get new stainless steel pushrod tubes and pushrod tube seals.

top

BMW - bmw2020_008.jpg13K

There's part of the problem. The valves were not seating properly.

top

BMW - bmw2020_009.jpg13K

While I'm waiting, replaced the oil pressure switch.

top

BMW - bmw2020_010.jpg17K

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?

top

BMW - bmw2020_011.jpg15K

Some assembly required. Piston and cylinder back on the bike.

top

BMW - bmw2020_012.jpg16K

Head back on the bike. Need to adjust the valves. Remember - torque, torque, torque, very important.

top

BMW - bmw2020_013.jpg13K

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.

top

BMW - bmw2020_014.jpg15K

It's the little things. Like which cable is choke and which is throttle. Don't ask...

top

BMW - bmw2020_015.jpg13K

Replacing diaphragm, jet needle, and spring. Make sure everything aligns and the jet needle is on the right notch (the 3rd notch for me).

top

BMW - bmw2020_016.jpg13K

I'm using a main jet of 145 and idle jet of 45. Lots of fun getting the new o-rings on.

top

BMW - bmw2020_017.jpg13K

Enricher gets new gasket and o-ring. A real Airhead knows it's not really a choke.

top

BMW - bmw2020_018.jpg13K

Ready to start putting back together with all new o-rings, gaskets, floats, float needle, jets, springs, diaphragms, everything.

top

BMW - bmw2020_019.jpg15K

Both carbs ready to go back on the bike.

top

BMW - bmw2020_020.jpg13K

Took the old petcocks zu (off) and put new petcocks auf (on). A bit of fuel petcock humor.

top

BMW - bmw2020_021.jpg13K

New Thunderchild dioide board. Determined a couple diodes were bad, but I sure didn't know it by riding the bike.

top

BMW - bmw2020_022.jpg13K

New brushes installed. This job should have been easy. Yup, should have been.

top

BMW - bmw2020_023.jpg13K

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.

top

BMW - bmw2020_024.jpg13K

Went with a Denso starter. There are several (cheaper) options to replace the starter, I chose this option.

top

BMW - bmw2020_025.jpg15K

New Bosch ignition coil.

top

BMW - bmw2020_026.jpg13K

New voltage regulator. I'm going to miss the pretty blue color under the tank.

top

BMW - bmw2020_027.jpg15K

New Thunderchild Ignition Control Module. This thing does so much related to the starting and running of the bike.

top

BMW - bmw2020_028.jpg13K

New light relay, why not?

top

BMW - bmw2020_029.jpg13K

Now simply called the yellow relay, it's for the starter, horn and various switches.

top

BMW - bmw2020_030.jpg13K

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.

top

BMW - bmw2020_031.jpg14K

The 'choke' cable splitter and the left/right cables were still available.

top

BMW - bmw2020_032.jpg13K

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.

top

BMW - bmw2020_033.jpg13K

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.

top

BMW - bmw2020_034.jpg13K

Nice clean install, lots of bright light. I additionally bought a flashing unit so the Denali brake lights flash. ATTENTION GRABBER!!!!!

top

BMW - bmw2020_035.jpg13K

New Michelin Pilot Activ tires for front and rear. I really like these on this bike.

top

BMW - bmw2020_036.jpg13K

Decided to buy a No-mar tire changer. Got a great deal.

top

BMW - bmw2020_037.jpg14K

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.

top

BMW - bmw2020_038.jpg15K

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.

top

BMW - bmw2020_039.jpg15K

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...
