Mine did exactly the same,mostly on the right side as well.
I turned out the mixture screw a little at a time till I got rid of the big pops. I now have the ocasional pop but its more of a rumble on decel.
Sometimes I now get stereo pops(thats cool
).
Turn your mixture screw out a 1/8th of a turn out on the right side,that will probably improve it,just keep an eye on your plugs to make sure you dont get too rich.
