Thanks Michael, appreciate everyone's feedback. Yes, I did check all the hoses, bolts and everything looked fine. The bike idles and runs great except for the popping.
Im taking it by Eurocycles today to have it diagnosed, hopefully it's just the mixture like everyone is thinking.

I think that if an air bleed screw had fallen off it would run VERY fast at idle, and I doubt one would have backed off in such short time.

However, I'm noticing a popping from the intake/air box when I'm just start accelerating sometimes. It doesn't happen all the time but several times on a ride. The bike has staintune exhaust which sounds wonderful and a dobeck module - for the exhaust. It was tuned by fast by ferracci so I stumped? Any idea what could be causing the popping?
