I have a 1975 cb550k for sale. I’ve had this for 8 years now. Completely rebuilt it when I first got it. I had it on the road for two seasons (inspected, registered and insured) and then put it aside for new projects.
The last few years Ive barely had it out. I always had the battery on a tender and started it every once in a while. A few weeks ago I was out riding it and it was acting funny (timing is off ). I found the timing advancing unit was seized. I ordered a Honda OEM replacement and installed it. The bike does run but will need to be adjusted and probably a balance of the carbs. Carbs were just off and inspected. Very clean inside. I truly hate selling this bike but I just have no time for this anymore.
I have a video of it running nice and smooth from August 20, 2025. The bike does run now but will need some tinkering.
This bike does have a Moto-Gadget M-unit Blue power module. An Anti Gravity lithium battery, all LED lighting and more. If you’re unfamiliar with the M-unit I can explain this over a phone call or you can look them up on YouTube. Everything works as it should and the M-unit allows for custom setup of the bikes lighting, starting, shutdown, alarm system etc…
I will throw in any extra parts I have for the bike to who ever takes it.
