Well back at it again trying to figure out what is going on. I still have that intermitant miss at lower speed. I have taken the fuel injector out and checked it for dirt and debris. No such luck. Air filter is clean. Checked the valves, right on the specs, I even replaced the stator as suggested. Does anyone have any other ideas? Will the yamaha programer show any codes for fuel? Do I need to take this to the dealer?
