In my Honda tech manual for my 1973 CL-175, it does show a mid-year change. The early bike (like mine) has one set of points and one coil with dual secondary outputs. The late-year Honda changed over to dual points and dual coils. I.e. one set of points and one coil for each cylinder. I'm wondering why they did this? Cost or better performance?
Whatever, this problem has me somewhat stumped. I'd suspected that maybe a coil can develop an internal path from the secondary to ground and thus cause this problem. I DID try another used coil but can't say I know for sure it does not have the same problem.
Also as another poster mentioned, I've wondered about unequal fuel-air ratios between one cylinder to the other. But the problem is not dedicated to any one cylinder. It is random. I've never spent any money to try to fix this bike since once warm, it runs fine and will do so all day long with issues.
