    Help: Zero compression, yes zero. 1979 CB750K

    Unfortunately I do not have a compressor in the garage, otherwise I would do a leakdown test. Here are pictures of the timing set at 1.4T, the position of the lobes @ 1.4T, the ends of the cam shafts and the timing marks aligned with the head. https://ibb.co/qWPXQxY 1.4T...

    Help: Zero compression, yes zero. 1979 CB750K

    I replaced all gaskets down to cylinder base, piston rings were good, no scarring or marking in cylinders, had to replace cam tensioner 'b' as it was broken. Not sure what else there is to disclose...

    Help: Zero compression, yes zero. 1979 CB750K

    1979 CB750K I'm at my wit's end. I've problem solved as much as possible, checked clearances, replaced gaskets, ensured timing marks are bang on (followed this for cam/timing installation as I found it much clearer than the Clymer manual...

    1979 CB750K m-unit blue ignition wiring

    None of the other config options solve the problem. How would one go about bypassing the m-unit for kill switch function?

    So I did the continuity test and there is no continuity when the kill switch is on “off” and there is continuity when it’s on “run”. That said; the m-unit already on configuration “C” for handlebar instruments which is: japanese/european bikes. On every other setting it functions the same way.

    yes black/white from handlebar is going to kill input. black/white from spark units/coils is going to ignition output. There is no "kill" output.

    1979 CB750K m-unit blue ignition wiring

    So I was able to get everything hooked up, the key works, the ignition is powered everything is good (Thank you!) except that the kill switch is functioning backwards. That is to say when it's in the switch is in the "run" position it's actually functioning as kill (confirmed on the m-unit as...

    1979 CB750K m-unit blue ignition wiring

    So i've re-done and cleaned up the initial image I posted. Is this what you're referring to? Is that key ignition what I'm looking for? In terms of black to lock and red spliced off of the wire from solenoid to m-unit battery power?

    The ignition switch in that image has 6 prongs where as mine only has 5 (the middle upper prong does not exist on mine). But it would be fair to say that it would be the same output? I am not using an M-button for this setup. The only black wires from the reg/rec are the one that connect...

    1979 CB750K m-unit blue ignition wiring

    I'm having troubles figuring out exactly how to wire up the ignition on my 79' cb750k. I've exhausted the internet and haven't been able to find a forum thread or wiring diagram that has gotten far enough to break down what I'm looking for. The basics: 1979 CB750K M-Unit Blue Revival Cycles...
