BACKFIRE ON DECELERATION

BACKFIRE ON DECELERATION
I HAVE KFX 700 WITH ALIEN DUALS WITH QUIET CORES, STOCK JETS, 3 TURNS ON CARB AIR SCREWS, ( PER DMC ) AND I AM HAVING MILD BACKFIRING ON DECELERATION. THE PROBLEM WAS WORSE WITHOUT QUIET QORES AND WITHOUT AIR ADJUSTMENTS. I HAVE TIGHTENED ALL THE BOLTS ON THE EXHAUST BUT THE BACKFIRE CONTINUES. THE 700 RUNS GREAT AT THIS ALTITUDE ( DENVER, 6000FT ) ANY SUGGESTIONS?

think about it this way, if you let off the throttle then it closes the slides and sucks gas like a choke , and if the exaust is hot then it lites the residuale charge of fuel/air, thats what causes the back fire in the exaust. the more air in the exaust then the greater the chance of back fire.
