This bike has been in storage for 35 years and is in pristine shape I changed the oil, drained all the old gas then refilled it with ethanol free 87 octane. The gas tank and carb look clean as new inside. It starts on the 1st kick with the choke on when cold. I will ride for a few minutes then it will bog down and quit. I can not get it started until after it sits a few minutes. After a couple of minutes it will start then quit again aftêr I ride for a minute or two. Thanks in advance.
Might be fuel starvation.
If fuel tank isn't properly venting, may test run with cap ajar to see whether condition persists.
Would also assure that the carb float bowl vent is exiting to open air.
If an in-line fuel filter is fitted, assure it isn't clogged.
Also assure that the petcock isn't clogged.
Basically want to assure free gravity flow of fuel from the tank into the carb.
Good Fortune!

Before taking the battery in for the test, would remove it from the bike, add distilled water as might be necessary to restore fluid levels, and then charge the battery overnight with a 1~2 amp charger. This gets the battery into its most presentable condition for the load-test.
If this is the same battery that was in the bike after 35 years storage, ignore the load test and install a brand new battery. The old battery may be worth trading in to save a core charge. Be sure to properly service and charge the new battery prior to installation.
Good Fortune!
