whinning noise 08 Strat

I get kind of a high metal whinning/whirring noise when i let off the throttle or downshift and let of the clutch. It doesn't sound like metal to metal but more something almost mosquitoish. If your a Star Trek fan the noise from The Wink of eye is what it kind of sounds like. If i let off the throttle I hear it and then grab the clutch its gone but downshift and let off the clutch there it is again. Kind of sound like pressure on something from the left side maybe front drive belt pullyish. Any ideas?

Thanks

My strat makes the same noise. Don't know what it is,hasn't got any louder. I just keep pouring the coal to it and it keeps taking me down the road. Sorry I was no help but I think it's a normal noise.

Noise

Dont know if you blokes have emergency flashers on your bikes but if i turn mine on noise gets louder so i reckon its the gen/alternator...

Could be what he posted above... Alternator does do lil sound changes I hear it. When I switch passing lights on and off. But only when sitting still can't hear anything when moving...lol...
Other could be belt tension, that can give you whines when either lil bit out of alignment, or tension changes. check them if its not the alternator. I like to have my bike up on cycle jack and spin the tire forward and backward. Too see if it is moving from side to side in pulley then I know out of align.

Whining noise

My '07 Strat makes a noise like this and I always thought it was either wind rushing through the spoked aluminum wheels under certain conditions or harmonics. I've also considered the rear wheel bearing...

Wink Whining noise

I think I figured it out, it's probably the wind whistling through my ears when I'm not wearing a helmet...
I did find a cure, install a set of Cobra Longshot exhaust pipes, drowns it right out...

My 1100 makes the exact same noise. It gets louder the faster i go. Then... just as i hit 88mph the flux capacitor lights up and then there's a very bright flashing and then...oops...wrong thread

YES!!! Had the same thing and dealer couldn't find it. Front drive belt pulley came loose. The drive pulley nut will back off and the drive pulley becomes loose. It will tweek a little bit and cause a grinding noise. Very easy to check. Remove the cover over the drive pulley. Inspect the nut and pulley. The repair manual states you have to replace the nut when removed. You can clean the inside threads of the nut and clean the threads on the shaft, then apply blue locktite when you reassemble. Torque is 100 ft lbs. and you also stake the nut. You will see two flats on the shaft. After you torque, stake the nut on both flats. Happy Riding!!
