I just purchased a 2001 banshee, and noticed when I get on the throttle it doesn't respond like it should with an instantanious burst, I previously owned a 2000 Banshee and never had ths problem, to me it sounds like it's not firing properly on the right side, it starts fine and idles fine just doesn't respond when you get on the gas, Does anyone know how to troubleshoot such a problem, I am going to start with the plugs and Air filter, clean the carbs could any of these possibly be in the right direction?? Any help would be greatly appreciated.
