Backfires when starting

[Knuckles]

Mine does this also but only when I leave the gas on. If I turn the gas off when refueling or parked at a stop, does not happen

Well I replaced the WP re-wire with a RIP ECM. All electronics are working - horn, speedo, lites, etc.
Bike will not stop backfiring when started. I replaced the Inition Control Mod., and coil, still same.
Will not stop mis firing.
I need some help here...please. This is NOT a case of a single back fire when starting up. The bike will not
run well enough to move. Continuous back fire and mis-firing.
Much thanks in advance

Are the plug wires reversed?
