Is gas getting to the carbs? Check the vacuum lines for a leak. Check the petcock and fuel line for blockages. Is the air filter clean?
Change the spark plugs and while you're at it before putting them in may sure they spark.

I'd say your pilot jets are clogged.
They are the smallest and easiest to clog. They control idle and slow RPM running.
Easy to clean but DO NOT USE A METAL WIRE! You run the risk of enlarging the hole which will adversely affect how the bike runs.
Soak them in carb cleaner, use a toothpick to dis-lodge any gunk, then use compressed air to blow them out.
On some carbs they are replaceable so it's easiest to get new ones (they are cheap). If not just be careful cleaning them.
Drain all the old gas and use fresh gas in the tank.
Also make sure the air filter is not plugged up.
Let me know if you need a hand.

Cause he's only got the one...

Steve, how'd you like that six-pack of battery I dropped off?

While you're draining the tank, do a visual inspection (with a flashlight NOT a lighter unless you'd like a Darwin award) for corrosion and rust.
