Hi guys, how are you?
I have an issue witth my Banshee: misfire and backfire on right cyliner at idle. It runs at first kick but in a few seconds right cylinder starts with problems. Right pipe gets hot but not like the left one.
-FMF Fatty pipes with powercore II.
-Stock reeds valves.
-Stock airbox and filter.
-Good sparks.
-Carbs have been rebuilt with repair kits.
-Left exhaust are hotter than right one.
-Carbs are synced. Air screw and idle screw are equal regulated.
What are most common causes of misfire and backfire ? What should I check?
Thanks everyone.
