Is it a whistle or a howl? Is it consistent with throttle pressure? Meaning if you are in the go pedal it does it, the minute u let off it gors away?
Mine has this weird howl and it progresses from low pitch to high. It is not consistent with throttle pressure and I notice it when I am pulling heavy loads up hill where my foot is int it. When I let off it's still persists.
