Help with CB900 custom

I recently picked up an '82 CB900 custom with 36k on it. I've got
several issues I'm trying to work out. First, what are the plugs
supposed to be gapped at?
Second the bike is cold-hearted to the core. If I do not start it
every other day, I nearly can not start the bugger. The only yhing
I've noticed is that plug one is usually pretty fouled, the others are
fine.

Any suggestions?

 

"Fouled" with what? Wet fuel, black carbon, grey deposits?

The nature of the fouling should lead to candidate causes.

All will be revealed. I'm serious. Hundreds of experienced/informed owners
of this very bike. On-line manuals, discounts on parts, folks with spare
parts, etc. And friendly/helpful, unlike some groups out there. No such
thing as a stupid question, even if its about blinker fluid or muffler
bearings.

In the short run, yes, they are cold hearted bastards. They want to be run
every day (mine is). They are extremely sensitive to low battery voltage;
they want to be well-charged, or they use all their energy to turn the
engine, with not much left for spark.
