Hi,

I need help with my arctic cat 400 fis 2007. I have a high pitch sound at a specific certain rpms in either high, low or neutral. See my clip at you tube.

If you know what this is, how do I fix it? I have had this noise for a year.

Thanks in advance.

Anyone had similar noise problem? If i give more throttle the sound disappears, and also at no, or little throttle. Its just in a relative small part of throttle range. So when you hear it in video i vary the throttle to let you see the change in sound. See speedmeter. Note It is in km/h note mph.
