back fire intake

Post by sean215 »

My bike been back firing from the intake like crazy. At start when I pull off and most of the time around 3000-4000 rpm. Bike idling at 1400. Recently I adjusted idling to 1000. And bike seen to run alot better. No intake backfire at start when I pull off. And rarely backfire around 3-4000. Anyone know what the cause of this?

Thanks

More than likely you have a leaking inlet manifold.
