I have noticed some firing through the airbox during the last 2-3 rides. It happens off idle while revving the bike a bit at a stop light or in more rare cases right off idle when pulling from a stop.
I had a short ride today to pick something up, 10-15min there and the same way back. The bike sat for about 15 minutes before I got on it to come back. On the way back it didn't do it a single time but on the way there it happened 3-4 times. I could almost get it to do it on demand by repeatedly giving it a bit of gas thus bouncing the revs(but not revving high, just getting it off idle).
I've read others have posted about this, but it seems that people live with it. Today seemed a bit much though. It could probably cause one to drop the bike if it happened at the wrong moment as the throttle tends to "fall through". Any ideas? First that came to my mind is coolant temperature sensor(if Vs have them) if something is indeed not quite right.
The temperature today is 15C/59F and the bike has about 8500 miles on it.
