Reviving this thread, because I'm getting the (masochistic) itch to re-wire my bike again... Wondering if anyone out there has taken the leap, especially curious about completely ditching the stock harness are re-wiring from scratch using the m-unit. I rewired a 1973 Honda CB350 last winter with an m-unit and it was an absolute pleasure. The bike is so much cleaner now, and the confidence level knowing the thing is actually reliable is the best part. The only thing making me hesitate is the complication of the ECU and ignition system, with all the sensors, fuel pump, injectors etc etc. Not very straightforward... Unless I get some good guidance, my strategy would be to just go for it and try to figure it out component by component. And if that fails, to rip out the ECU and throttle bodies and install an Elektronik-Sachse ignition and a pair of Keihin FCRs and just be done with the EFI system. I do want to give it a shot though. Wouldn't be happening until the winter anyway, but thought I'd reach out and see if anyone else had done it, start the discussion. I am aware that I am opening myself up to severe flaming, but I'm ok with that.
