My Banshee runs great at idle and on the top end in the powerband, but it acts up bad when at a stand still and I go to take off. When the engine is idoling its fine then when you go to take off it sometimes sputters and acts like its not getting gas. The jetting is right, coil wires are connected good, and the filter is clean, also the plug wires are good as far as I can tell what else could be the problem?
