Topic: Spark arcing from spark plug cap

Forget Clymer, you need the specs from a genuine Honda manual

[...] I ordered this Ignition coil kit from 4into1 and I'm just curious about resistance.

That set of coils would also be my choice.

As a matter of fact: that set looks ideal also for CB Fours with conventional breakerpoints ignition. Just add a 2 Ohm ballast resistor in the primary route. I favour screw on connections like these coils have. I can't comment on the quality of these particular coils though.

I don't think my coils are bad, I don't trust the Chinese quality coils and I do have a spare set of OEM ones if my current OEMs are actually bad.

Replace the plug in any case. BTW, did the hole in the old cap look like it had burned through from the arcing, and was it in the same location as the arcing now?

I'll run over to my parts store tomorrow and grab some new plugs.

I believe the arcing is in the same place however the old cap looks like it got chipped rather than burned.

well that cap is #$%*ed for a start.

That's the old cap, it's still arcing with the new cap.

I've been making due with the Clymer but I'll see if I can find one.

There’s nothing for the 1982 CB650SC.

Did you replace the spark plug yet?

Any updates???
