Also, make sure your idle is set around 1100 rpm. A low idle can lead to backfires and stalling.
Lastly, a failing petcock (or running out of fuel) will cause the symptoms you mentioned.
Thank you, you are probably right. I had recently had my cables replaced with longer ones to accommodate my 2" risers - they probably didn't adjust the idle speed screw properly.
Exhaust leak is highly unlikely, I had the pipe tig welded. And my petcock is the genuine Yamaha Raptor.
I'll adjust the idle and see it it gets better.
