Realized I wasnt getting all the horsepower, figured it was the carbs. Started troubleshooting and determined that only 3 cylinders are firing. 3 of 4 sparkplugs are dirty and 1 looks brand new. Thinking its either the ECU or a wiring issue. Does anyone know where i can find a used ECU? Brand new is 800$. Part # is Yamaha 3JP-82305-13-00.
