I got it running when I bought it in '95 but it eventually lost compression and sucked trans oil on the right side.
All three coils are powered by the same wire. They each have a trigger wire. I switched trigger wires and found #1 is dead, looks like it leaked some spooge, now crusty. #2 has no signal going to it. I may try swapping points on that coil. It's hard to mess up the wires as they have a three prong plug and are color coded. I just won a trio of used coils off E-Bay for $12.00. Also has a strange aftermarket black box running between the power wire and the coils labeled ARC. I may yank that after the coils get here and I have all three sparking. Any more advice is appreciated.
Great photos and stories all around! I don't own a CB-750 but have a '71 CL-350 that I'm about to put some dual purpose tires on.....and fork seals.
