I have had a noise from the front area,almost sounds like tire noise from a cupped tire but my front tire looks fine.I tried leaning hard in corners to see if the pitch of the noise would change but still the same.So I checked the bike over could not see anything loose and the noise gets noticeable once you pass 40mph and as you go higher in speed it gets louder.
So I am going to do a test with my air compressor but I think the noise I hear is my cooling fans spinning from the air flow through the radiator at higher speeds.Anybody else experienced this?
My bike is a 2012 Voyager with the heat kit all around the radiator.I am thinking of removing it and see if that helps or even locking the fan blade in place for a short ride and see if that makes any difference.the noise sounds like a fan hummm like when you blow compressed air through a fan and get it spinning too fast.Hense my thinking.

Hey man, I panicked the first time I heard my cooling fan. Apparently this is normal for it to be so noisy.

So it appears not to be my cooling fan but an over tight belt drive.Re-adjusted the belt a little looser and the noise seems to have gone away.

I've seen this stated as a fact many times but my question is why do Kawa engineers specify an over tight belt? There must be a reason or do the dealers when they get a new bike check all the settings & tighten to what they think it should be?

As an observation - could it be like using a torque wrench on a nut or whatever. You tighten till the set torque is reached BUT this doesn't take into account the condition of the nut/bolt itself which may be lubed (or dry) or dirty or whatever. The reality doesn't necessarily match the indicated torque so the specification isn't being met.

This time it was overtight because of me.I removed the wheel to have the commander 2 mounted and reinstalled the rear wheel myself.All seems ok now.
