Backfiring


Backfiring is a symptom of being too lean, not too rich. Clean your jets, synch the carbs and adjust the PMS.

Yamaha vstar 1100 back fireing


Re-jetting the carbs may be needed.
Imbalance of air/gas ratio will cause backfiring among many other things. :)

Other considerations:
Have the timing and valves set.

After market pipes will also increase the Poping sound when you let off the throttle. (not really backfiring but annoying)
Removing and plugging the AIS system will stop most of this.

Good luck!
Hope this helps.

Stalling


does it have a fuel pump? It could be going bad.. if not, it could be a bad battery...but since it looks like a 2008 its doubtful and could be just loose or dirty connections in the battery circuit.

Engine backfire


try pulling the choke out a little and see if that doesn't help.  If it does that is a sign that you are running too lean and need the jets in the carb increased or just the air mixture screw adjusted.  If the coke test doesn't help, please tell me more about how and when it acts up. Like after the motor is warmed up does the backfiring quit?
