I have a rough running and generally lack of idle on my bike (a 1979 CB750K UK bike) when I saw another similar post.
I believe my wiring may have been swapped on my coils as my +ve connections are the yellow and blue cables, could this be my issue??
The bike will start however it is not happy to idle below 2K revs and generally sounds like it is running on 2 cylinders as it is very knocky.
I have done the electrical tests as per manual and everything seems to be Ok but if I disconnect a wire from coil 1 the bike runs the same.
I have swapped coils over and the fault is still the same on coil 1 (which is now coil 2 if that makes sense) so I'm assuming the fault lies further back.
When testing the pulser assy I get a spark across plugs 1 and 2 but it does seem to be quite weak (the plugs are new).
I'm not sure if one of my spark units is faulty as it seems to have leaked most of its potting out also, although I have changed these over banks to test and I still have the issue on cylinders 1 and 4 on pulling the coil cable she runs the same.
