Any interest in attending the El Camino show in Torrance this October?

Stephen Hughes-Jelen — Tue, 08 Sep 2026 18:31:34 +0000

Is there any interest in SoCal owners (OC/LA/SD/Ventura/Riverside or anyone that wants to come) mobbing the El Camino classic motorcycle show in Torrance this year? It's on Oct. 10th, and only $20 to show.

If there's a lot of interest, I volunteer to contact the organizer for a heads up on a rough number of airheads appearing... I'm kinda looking for a way to meet airhead owners, as there doesn't seem to be many single-day close-by events near me.

Airstore: RIP

It's a sad day when ZERO club hats are available at the Airstore. This is not acceptable. Obviously they sell so let's get them ordered.

Looking for some electrical wiring genius on R75/7

Tim Cubbedge — Mon, 31 Aug 2026 23:42:38 +0000

So my '77 R75/7 is getting rebuilt from the bottom up. Needed a new wiring harness due to condition of original and many wires were bypassed or spliced or just not there. It was a mess. I watched several videos from Brook on the best way to do it and and everything looked great after I double checked all connections. One thing I noticed is that my left handle bar control only has 2 switches, one for horn and the other for hi-low beam. It doesn't have the 3rd witch which I guess turns the lights on/off??? MAX BMW shows this as a yellow switch. Anyway, once all connections were made, I performed a functional test which Brook performed in his video. I test in Park mode and then full ON.
My observations as follows:
In Park mode, both the parking light and headlight come on as well as tail light. I don't believe headlight is supposed to come on, only parking light.
In full ON, no headlight, high or low beam. All other tests worked in the full ON mode, horn, dash lights, brake light and turn signals.
Attached is a schematic which came with the harness. The items with the X are the items not on this bike. Any suggestions to get the lights on when in full ON mode versus Parking mode? Because I don't have the third switch, there is an open terminal on the head light relay (86) and one less gray wire going to 58U on connection board. These items are all shown on the attached schematic!

R75/5 wiring retrofit

Daniel Clepper — Sat, 29 Aug 2026 02:08:04 +0000

I recently picked up an ‘73 R75/5 toaster tank with a blown engine (previous owner installed an R100 oil cooler w/o the white o-ring and ran it till it seized). I’ve got an ‘82 R65 engine sitting on the shelf. Mechanically this seems like a pretty straightforward thing to swap in no question there.

My question is concerning the electronic ignition. It’s my understanding I can’t put points (not that I really want to) on the R65 so I will need to keep the bean can. Has anyone spliced a factory electronic ignition into an /5 harness or am I better bringing the whole R65 harness with me? Not sure where I’m going to mount everything so looking for advice.

The rest of the R75 is in great shape so I don’t really want to do too much moding to the frame I’d like to keep the headlight bucket intact if possible.

Cannot reinstall rear wheel R65 1982

jehu hand — Sat, 29 Aug 2026 01:07:36 +0000

I had the rear tire replaced on a barn find. I cannot get the rear wheel back on. With my 1979 it just slid right on, but the wheel hub will not go on. My plastic Euro motor caliper says the hub is 51mm in diameter, exactly the inside diameter of the hub. So it might be a tight fit, although I did remove the wheel easily. What do I do? Am I missing something? I don't have any special clamp to press it together.

Mark D Helm — Mon, 24 Aug 2026 15:35:42 +0000

I've been riding with a Rabid Transit for 2 seasons now ,and I have only seen 3 others on Airheads . It was at the last BMW RA meet in Chippewa Falls ,Wis. this summer . They all look nicer then mine . But I was just wondering if there are more Rabid's outside of the Mid-west. Mines on a white 1973 and a 1/2 toaster tank .I think it looks nice . Well ,have a cup or a cold one and tell me about yours.

Jon's R100 rebuild

Jonathan Cardin — Sat, 22 Aug 2026 23:28:50 +0000

I've fairly recently come into the possession of a 1984 BMW R100T(?) and I've been slowly gathering odds and ends to rebuild it. I'm still very much at the beginning, but here's a link for all the pictures:

https://drive.google.com/drive/folders/1ktre-hODSUB7CXO32SDStgoahbHwOi81

The wiring is a mix between not bad and completely screwed. Some rodent took exception to it in the past.

I brushed the frame down with a wire brush after these pictures and coated it in rust converter to stave off any further decay, of possible.

Thoughts?

1977 R75/7 Piston Oversize

Tim Cubbedge — Thu, 20 Aug 2026 16:07:44 +0000

Probably a dumb question but......Is there anyway to tell if my pistons have ever been oversized? Performing a top end gasket replacement and I was just wondering. The bike has about 120k miles on it. Can post pictures if that helps.

Question about 1978 R100s frame damage

Anonymous 70727 — Mon, 17 Aug 2026 02:05:42 +0000

Hi All,

I am looking over a new to me 1978 r100s. I discovered some cracks in the frame (see pictures attached). One is where the rear fender mount connects to the rear sub frame. The other is in the left-side flat gusset plate at the steering-head/neck area. A previous owner appears to have noticed this second one, applied something (some kind of epoxy?) as a fix, and then the frame was powder coated over the crack. Are either of these areas load bearing / require diagnosis and welding? Should I be worried?

Thanks,

Allen
