I agree with Beddhist. I would look for a cracked carb rubber first - you have the classic symptom. "Popping" and "poofing" under deceleration could also be caused by a leaking exhaust system - a weak point on the bike (if it has the original).
Other things to check would be to drain the tank completely and flush it out with clean fuel: if it is the steel one there may be particles in the bottom, stopping the fuel / blocking your main jet intermittently.
I would also change the oil and check the valve adjustment as a matter of course on a new bike too - no matter what the previous owner says, you don't know when it was last done.
Good choice though.
