I am relatively new to posting here and have not posted much. I am still under the learning curve, so please forgive if this has already been posted.
This is an interesting modification that I found on an West German website. A 2018 Street-Bob is converted from EFI to carburetor, with the stock CAN-Bus completely removed. Going "old-school" with new engineering.

I applaud this this guy ... he’ll be the first guy riding after an EMP goes off in his region.

Actually, I think Chucky-x who is registered here at this forum is an author of this invention can tell us more

Personally, I would love to have that idle and throttle response. However, with S&S cam the idle would be prettier. I considered converting my future bike to carb for that lullaby sound but would like to have a functional digital display like in his first
and second video

Wow those are some reactions..The Altmann ignition are pretty good..they have a programmable timing curve, rev limiter range etc..lots of folks have been doing conversions to their twin cams and sportsters with these systems for a while now. (even used in some beemers and V8's)
At the base of it the M8 is still an engine, so why not..there was a Speed Merchant Softail FatBob at the Mamma Tried show last year which had a carb on it. I was actually waiting for this guy to do this, it just put a smile on my face when i first saw the video almost a year ago.
Yes EFI is great, im all for it but Carb's are simply cool (and yea having too many will make you fat too )
Peace

I am no mechanic that’s for darn sure. What I would give to have just an ounce of the talent and mechanical ingenuity that I have seen here on this forum. I am sure many of you guys have a better grasp on what he did, than I do. To see the M8 retro engineered is pretty interesting. It’s amazing to me he had the wherewithal (and courage!) to make those changes. With the bike unencumbered by BCM and EFI, I wonder what type of power the motor can produce. AND, as Ip said, the idle is pretty cool.

I love how times change.
1995 - "Stupid Harley with their shitty fuel injection, I'm gonna switch it back to carb, that'll fix all these bad running issues..."
2019 - "Stupid Harley owner, why would he switch his M8 back to ancient technology? It'll run worse, less power, etc..."

Also at end of the video when the bike actually sputters and stalls, and the guy slightly chuckles..that's soo classic man, i love it
The title of this thread is misleading...CAN bus is not actually removed..the Altmann system works with the stock wiring harness by using signal from the CKP or crank position sensor for its timing. U can see from the video that the oil and the check engine lights are on. Bet the ECM is going crazy unable to find the signals for CKP, TPS, IAC, MAP etc and putting out codes all over the place
Now see why this is soo Awesome and funny (knowing ppl's reactions) at the same time.
