backfiring on deceleration

I know you have B-O plates, but do you have stick coils. New spark plugs does not mean good plug wires.

No stick coils.  Is there a way of correcting the possible no spark problem without spending another boatload of money on stick coils for this bike?

If the coils are good, Murph's sells a rebuild kit.

Thats one option.  Unsrew the plug wire from the plug boot.  Look and see if the inside of the wire is green or discolored.,  Trim about ¹/₄" off of the plug wires and screw them back into the boots and see if that makes it any better.  The manual has a good check list for testing the coils.  I just dont have mine with me.

I was able to determine that it was a missing stopper on the middle carb.  Prev. owner had taken a small piece of vacuum tube and inserted a self tapping sheet metal screw in the end and I guess my riding it had caused it to loosen.  Put on a cap and it runs like a top again.
