I am repairing a Honda CB 500T. After finally getting it started, I noticed one exhaust gets extremely hot; the other not so hot. There is a small amount of backfiring as I rev it up. Any assist would be appreciated.

2 likely causes.
#1: Carbs unbalanced. Could be dirty, with clogged jets, sticking float, or just not balanced to each other.
#2: Valves not closing properly. Could be bent valve stem, out of adjustment, or a piece of crap (carbon, etc.) not letting it close all the way.
The backfiring indicates carbs. Older bikes fire the spark plug on the exhaust stroke which will ignite any unburned gas that comes out. Check your plugs, see if it's starting to foul in that cylinder.

Some good answers so far.
Your bike has 2 sets or points. The points for the cylinder with the cold pipe, may need adjusting.
