Get a service manual.
there are two ways to go. both time consuming and of moderate difficulty.
My favorite is to remove the trunk, saddlebags, rear fender as a unit. Then the tire is in the open to work on. Not an easy job.

Sounds like the charging circuit is breaking down causing a strain on the alternator and making the motor struggle.If it picks up on the throttle then this may be the case.
Check all the earth connections as these have a habbit of corroding and causing a high resistance.

I have a few 1977 GL-1000 bikes.
I thought one was overheating but it turned out that the 9 volt regulator was fried and was putting 12 volts to the temperature gauge. Temperature was really OK. The fan switch is probably not lying

Get 4 quarts of JASO MA certified motor oil. I recommend synthetic , it will shift better when hot. Amsoil is a good choice. Place an oil pan under the front of the motor. Use a 6 point socket to loosen the bolt on the round finned oil filter cover on the front right corner of the motor and spin it off.Take the oil filter out of the cover and make sure you save the washer that will stick to the rubber seal. Pull bolt out of cover and replace o-ring. put bolt back thru cover, first slide on spring,then washer,and then filter and spin back onto motor pressing filter against engine case. Snug bolt but do not over tighten. Now remove bolt in the middle of the front/bottom of motor(large one in middle , NOT small one under water pump). Check aluminum washer,if bad replace.After oil has drained put bolt back in , do not over tighten.Take off fill plug on right rear corner of motor(by final drive shaft) Using a funnel pour in 4 quarts oil (3.9 is correct amount, 1/10th quart does not seem to bother anything). Put plug back in , start up, and check for leaks.
