Hello new here but not new to vintage Honda's. I always seem to figure out my own issues but I seem to have hit a dead end here with this one. Its an 82 cb750c that's all original. The carbs are clean and functioning perfectly so I'm going to rule that out for everyone. The problem is somewhere in the electrical side of things. When I got the bike non running I put new plug wires and ngk caps on it. After starting it it seemed sluggish on revv up. Felt the head pipes and 1 was cold. Pulled the ug on it and it had spark to it....weird. while checking for spark the bike started on 3 cylinders and for kicks I revved the engine while grounding the plug....the spark disappeared. It returned when idling. I'm running ngk plugs. After more tinkering and checking grounds and connections theproblem seems to jump around between cylinders. Had it on 1-2-3-4 act up. Both coils check at 11k ohms on secondary and 2.6 on the primary. Is this within specs?? I get about 11.xx volts feeding the primary side on both coils....guessing there's a but if resistance somewhere in the system. Battery is new. Any help is appreciated!! Thanks.
