Hello, Ron, and WELCOME to KZrider!
We're glad you're here!
Four brand new NGKB7ES sparkplugs would be as good a place to start as any.
If not already at hand, am thinking a shop manual would be most helpful.
Here's one of several current ebay listings.
Good Luck!

always check the intake rubbers many have gotten old and have cracked between the mounting flange and the rubber letting your carbs suck to much air. Also I would sugest a compression check bad rings or valves could be a issue they should have at least 115 pounds of compression to have power and a good running bike it can run with lower or higher compression I think the new engine compression is around 130 or 150 PSI. I use B-12 carb liquid cleaner in the gas to clean the carbs along with B-12 spray to clean anything I can get to, I have found to use both will do a better job cleaning because the spray is there for a short time and what is in the gas will keep working while the gas is running through on a normal path hitting all spots the spray missed
