    Thanks for asking. Mostly waiting for COVID delayed parts now... got a few more things to work on though too. Caliper repaint went well, used VHT caliper paint. Working on some carbon fiber skinned headlight buckets too. One practice one and one I'll use. I'll probably sell the test one as it has come out quite nice too . Also working on carbon fiber skinned, 3D printed inserts, to replace the fork reflectors. When they're done the BMW lettering should be very slightly embossed, so should be very subtle!

    Yeah the orange NYALOX on a cordless drill was definitely the best thing I tried. It doesn't seem to take any material away, just leaves a fresh aluminum! Steel brushes were too extreme and gouge into the aluminum, and the brass brushes just leave everything coated with brass.

    I'm not yet sure of self-painting with rattle-cans is gonna leave me with something I'm super happy with... time will tell, so other options are a) professional paint job and b) powder coating (which I think is the most robust). Getting deep into the fins is pretty hard. I kind of wish I had a blasting cabinet and then just used something that isn't too abrasive. Harbor Freight does em cheap!

    Thanks. .

    I have a HF blasting cabinet. It's buried in the basement under a ton of stuff. It's "OK"....makes a huge mess and my wimpy compressor can't really keep up.

    Starting to come together

    Got a few chips to the motor paint job, so I'll touch them all up at the end of the project!

    I'm working on a 3D printed battery box that's gonna go behind the airbox (that's why its not present in the photo)

    Merry Christmas and Happy New Year to all!!!

    That's coming along!

    I might have to PM you about the engine paint.

    Making progress... I've started with electrics the past week. I've opted for a VAPE full ignition and then full MotoGadget electrics. Once it's all in, I'll take some snaps, but in the meantime, I did finish the fork inserts (reflector replacements). They came out as I'd hoped, which is barely embossed at all, but with the light on them, its clear they say BMW

    Haven't seen an update in a while, how's it going? (It's been cold here, so my project is stumbling along).

    Coming along nicely

    The project is looking pretty good.

    Might I ask how you mean to deal with the electrics? Are you going to make harnesses, or adapt the stock ones? From what I have seen in some cases of motorcycle modifications to bobbers, or cafe or custom bikes, the electronics can be the most trouble down the road.

    Not saying you haven't thought about it or haven't planned how to make things work, so far you impress me as knowing what you are doing.

    I may be poking, but I will tell a tale of my friend's experience with buying a customized bike. Not a BMW but a Harley. He bought the bike from the guy who "customized" it, and it was a neat bike, cool looking. But, it didn't charge the battery. In fact, the alternator didn't work at all. The previous owner who had done the work, had given up on it and sold it to my friend, not telling him this of course. After a couple of rides and finding the bike was running only on the charge in the battery we sat down with a test meter, test light and wiring diagram. After a few hours of poking and prodding, we finally figured out when the PO had changed out the speedometer for a "custom" unit, he had neglected to make amends for the lack of a alternator charge light bulb. Viola! Like the BMW airheads, this bike needed the bulb to be in the circuit in order to complete the circuit for the charging system. Take the bulb out and the alternator wasn't energized to charge. A simple fix but, it should have been thought of by the builder of the bike.

    Okay, I have added my two cents, LOL, I can't wait to see the finished project. My friend has a Bober sitting on his lift he was building for a fellow, it is not complete because the owner had a stroke. Some day it may get done, so far it is neat looking as well. St.

    Hi!

    Yeah, un-heated garage has kept me from big jumps, but saying that I've taken lots of little steps and am nearing assembly completion

    - Vapor blasted carbs came back, so I rebuilt them and got them fitted
    - put all the in-bar wiring together and finished up the handlebars
    - built the clutch cable
    - Installed front brakes and bled the new lever/MC
    - Did a test fit of the exhaust pipes
    - Finished the carbon-fiber skinned battery box - went for the "forged carbon fiber" look. The photo shows the lid, which is 3D printed, but not yet carbon fiber finished.
    - Tail light fitted
    - Wiring!!!

    Expecting high 50s this weekend, so I think I may get close to the point of being ready for a first start.

    Thanks! excited for the first start and then the first ride! But I'm a wuss when it comes to cold weather, so I can imagine the first ride will be when we hit the 70s :P

    I have ditched the entire original electronics system, including the starting/charging system. I've gone for the moto-gadget M-unit system to replace the electronics and then a "VAPE" CDI system (Czech company doing modern CDIs for old bikes). I've also switched out to a lithium battery, and the VAPE system has a reg/rec suitable for lithium battery charging. The battery swap from the original must have shed at least 20lbs! One of the photos, I just posted above, shows some of the electronics (which I've already neatened up a bit). The MotoGadget stuff is not too cheap, but it's really remarkable. Does away with most fuses/relays etc.

    Like I said

    Like I said, so far you look like you know what you are doing, now reading your latest post and looking at the pictures, it looks like you have the bases covered.

    Not that I am going to be building a bike but I'm going to look over the web sites for the companies you are using. Cheers, St.

    Coil location...?

    Looking good, man! Nice clean work.

    I'm curious where you put the coil (I'm assuming it's a dual output Dyna or similar)......

    Another pic or two of the electrical set up would be cool to see.

    I'm wiring a 1965 R50/2 conversion project in a similar fashion right now. As you say, the Motogadget stuff ain't cheap, but it sure is good!

    Thanks!

    Here you go. So the coil is adjacent to the m-unit, but on the other side. Now MG instructions says that there has to be a distance between coil and m-unit, but from digging deeper, the consequence of not doing this is that there can be some RF interference at certain RPMs, which ultimately may automatically switch on a turn signal or something annoying, but not serious. I fabricated the m-unit mount from pretty thick aluminum, which should shield it. If I experience any issues, I'll make another shielding plate, and ultimately if any bad issues arise, I can move one or the other

    btw, the coil was part of the VAPE CDI system

    That looks like pretty clean wiring. Well done. I'm chasing a voltage draw on my 640A right now and instead of it being one component it's 2. Weird.

    Agreed! That cable rub looks terrible

    I want to keep that stock though... but I have a new replacement on order
