Hmmm! Tend to forget not everyone is a MotorVehicle Technician as easily back in the day. I did have my 400 run on 2 cylinders and noticed the performance drop off straightaway, cause was the yellow wire to the coil disconnecting.Thank God Honda strap down Fuel Tanks with rubber which is quickly detachable, my BSA Bantam stopped on me one night 3 miles from home in the dark, pushed it all the way home to find next morning the bullet connector to the contact points had come apart, having a British bike kept you fit.
Are all the exhaust headers the same temperature, ie, equally bloody hot when you've been riding?
Once you have eliminated the Sparking you may have to look at fueling. If valve clearances are good then I would check the float level for the cooler cylinder.
You mention that when you put No. 4 lead onto No. 3 plug the exhaust then got hot. Is there a chance that it was incorrectly fitted in the first place? Have fun, it's a great hobby for keeping the old grey matter active. Mike.

Mike.I don't think so, since the spark is is 'a redundant spark' I expected it to 'work' at the other end of the stroke to at least prove the fuel is getting through. So I think the leads aare all in the correct order. I just swapped them as a logical elimination step.I will take the tank off again, tomorrow, and follow the leads to make sure they are #1and#4 and #2and#3.. If they aare not, then it needs new cables as they are not reaching anywhere else.PS, I am having a good time doing this and learning.
