Hey guys, I'm hoping someone can help me out with a problem I'm having on my 1980 CB750F.
The bike fires up without any issue and drives fine for about 10 minutes, then I'll lose cylinder 2&3! I need to let the bike cool down, then it starts up fine again...but after another 10 minutes or so the same thing happens.
I started working my way backwards from the engine, and I've replaced the plugs, wires, and coils. I have also swapped the CDI leads to see if one of them might be bad, but so far I'm out of luck.
I'm almost positive it's an electrical-related issue as it seems to happen once the bike gets warm. I figured if it was Carb-related, I'd have problems starting or idling the bike at start up.
I'd love to hear your thoughts, if you've had something similar happen.
