My Bike Stalls at Stop Lights

I just bought an 89 Yamaha Radian. The seller said the carbs were just serviced, the battery is new and all the fluids have been flushed and changed. It rode fine when I test drove it.

Over the past two days, (I bought it 3 days ago) every time I stop at a stop light it will stall if i don't have the throttle rolled on a bit. It doesn't stall right away, but slowly the engine will just cut out even when I have the clutch held in or the bike in neutral. I'm not sure what the problem is.

When I turn the bike on, I have to give it a little gas but i can't let it sit there to warm up because it will stall out. Even when I have the choke all the way open.

Can someone help me?

Thanks,

Denise
