Keep in mind that your at sea level, the Phantom is actually designed to run pig rich, especially all the more so during the 300 mile breakin period...That needle valve in the JRL BoFeng carburetor needs to be no higher up the needle than the middle groove at sea level elevations which is also taking into consideration high temps and high humidity levels you have in Florida.
What you call "popping" is actually a four stroke sound when at idle or at a cruising speed not under load and is aiding in lubricating as well as cooling the motor which runs hot to begin with.
You DO NOT want to overheat a Phantom motor if you expect it to last.
