I have a 2001 426 and was riding it yesterday and found out that when I have the throttle steady it seems to sputter a little. I am not hitting the rev limiter as its just a half, consistent steady throttle. I was wondering if this is normal and they are made to either throttle or not? If not normal, what could be causing it? It is fine with everything else, when I throttle it hard it is perfect, when letting off the throttle it is perfect and returns to idle fine. Not sure on this one.
