Default bike stalls at stop

This has happened 3 times in the last month. When I come to a stop sign , my rpms drop and the bike stalls. It sounds like it is starving for gas. But it starts right back up and I don't have any problems the rest of the ride. Any suggestions would be appreciated.

My 07 Heritage did the same thing. I looked at several things, but it was the throttle motor. A little cleaning and it is fine.

I assume you close the throttle when coming to a stop so I would be curious if it stalls while stopping or just when you actually stop. If it does it when actually coming to a stop could it be the clutch dragging? I always start in neutral if possible and the few times I have started in gear after I stalled the engine I could feel the drag. The drag might be different depending on how hot the clutch plates are. If it stalls before coming to a stop, I would go with the idle control motor mentioned above.

Intake leak?
Throttle position?
Fuel pressure?
I would think if it was a sensor, it would throw a trouble code for a sensor out of tolerance.
Could be a lot of things. I'm sure that one of the mechanics on here will post what, in their experience, is the best place to start troubleshooting. Keep checking back.

Buzz, I'm thinking its EFI if he's asking about O2 sensors.

My guess is that you are experiencing a drop in voltage someplace. Perhaps there is an electrical drain on the system when you put on your tail lights? Maybe a brake light wire is grounded out?

It's possible that the engine speed is set too low,do you have a tach? RPMs should be 950-1050 when hot.
