I just bought an 07 Yamaha TTR-50 dirt bike for my son. The bike idles fine and runs ok, but when you get it to wide open throttle, it sounds like it sputters and spits. It has nothing done to it but an aftermarket air filter. There is no filter housing like stock, just the new filter that is like a k&n or something. I have cleaned the filter, and replaced the spark plug. Does anyone know how I can bring the carb back to the original settings? It looks like the previous owner messed with it a little.
