my 450 doesn't run rich but it does backfire. They tell me it is normal in certain decelleration situations it will do that,but it really hasn't backfire since I installed the K&N AIR FILTER

I believe the valves being out of adjustment can cause the engine to backfire...

check the vaccum line to the fuel valve and make sure it is totally dry, sounds like what mine was doing, it was sucking gas in ahead of the carb.

mine is not EFI its a carb, right now I just plugged both lines and running on prime, might be worth a look to find how your fuel system works (fuel valve). I have a 2005 eiger, the suction comes from engine (intake side of carb) that opens the diaphram on the fuel valve, diaphram seems to be bad, a new one is 90 bucks!
