I'm with nujohn. Retighten your slipons and use harley clamps if you have 'em.

I had 2.25's and it popped like crazy. Went to 1.75's and it was alot better. My bike's an EFI, though. You're in a better position (read cheaper fix) with a carb.

Try screwing out the idle mixture screw 1/2-turn at a time. If it has never been adjusted it may have a plug on it that must be removed first.

Pops or blubbles on deceleration? It sounds like your main jet is too big; go back to 45/190 and try it. play with you needle height.
Don't need no stinkin dyno for a carb.

The main jet has nothing to do with the mixture at 0% throttle on the CV carb, which is what he is describing. If the idle-mixture is too lean it can cause popping on decel. I suggested he screw the idle-mixture screw out a bit at a time, trying it at each setting until it stops. Another suggestion to seal-up the muffler may also help.
