Hi, Anonymous and the usual suspects are:
1. Idle speed improperly adjusted.
2. Air fuel mixture screws not properly adjusted.
3. Inlet system air leak.
4. Leaking accelerator pump.
5. Loose low-speed jet.
6. Plugged low-speed jet.
7. Contaminated or plugged low-speed circuit.
8. Enrichner valve/choke not seated or leaking.
9. Multi carburetors out of sync and need to be balanced.

under the left side of the gas tank you will see i black knob/screw at the end of what looks like a hose. the knob faces the rear of bike. that adjusts the idle. its real easy to find and the only adjustment you can make to the carbs.

Buy 4 quarts of motorcycle oil. Motul, Maxima,etc. Oil filter and a crush washer, 14mm. 10/40, or 15/50 is ok. Chaz Moto DC

Hi and welcome to FixYa,
Initially, inspect the burn colors of the sparkplugs. If they are very light in color, then it would indicate a lean mix
Offhand, a lean mix andsputtering would both indicate an air leak; too much air, too little fuel. Either or both could be caused by a torn or out of position air filter or the air box not properly sealed. Aftermarket free air breathers/filters such as those by K & N and/or non-stock exhaust could also cause this if the carbs were not re-jetted. In some instances, the needle height might require adjustment.
Good luck and thank you for asking FixYa.

yes, old gas can cause that a little bit. i recommend putting in fresh gas and adjusting the idle from there to ensure there are no other problms.
