Dunno about any 'wise words', or even if this truly does work, but just between you'n me (don't you dare tell anyone else tho, I was sworn to secrecy!

) I know of a few Ozzie Spyder owners who believe they've got this whine fixed - they've had a disc cut out of either a thin metal (galv iron sheeting/tin??) or thin rigid plastic sheet material that's of the correct diameter to fit into and fill the entire inner depression area in the front pulley (excluding the raised boss in the middle for the securing bolt - the discs have a hole in the middle that fits snugly around that raised boss) and they've glued/affixed this disc into place to cover/seal the holes in the sprocket, stopping any air passing thru as the sprocket rotates.
Their claim/belief is that by covering the holes in the front pulley, the air flowing thru/around the spinning front pulley can't go thru those holes, and since it's that air passing thru the holes that makes the noise at those speeds (sorta like the air going over the tapered lip on a tin whistle) the whine goes away. I've ridden a couple of these Spyders, and personally, I'm not all that sure either way, but then again, I am pretty deaf in those auditory ranges (apparently I spent too many years up close to things that go bang!

) and while I could very faintly hear what some might consider to be an annoying wind type whistling/whining noise if I listened carefully at those speeds
when I didn't have my Shoei GT-Air II on, I really couldn't hear that noise at all once my helmet
was on (yeah, they are meant to be one of the best helmets around for cutting wind noise?!), I couldn't really tell if there was any noise there before, or if there was any difference when I rode those Spyders again a few weeks later, after the discs were fitted.
However, if you want to try it, I don't have any pics, but the discs are fairly simple to make & affix - they're just a thin material disc cut to the right size to fit into the depression in the pulley but going around the raised boss bit in the middle, effectively just covering the holes in the centre of the pulley - one, IIRC the metal/galv tin disc, was pressed in and glued directly to the face of the pulley while it was in-situ, and AFAIK, it's still there some 30,000 miles later; while the other placcy discs have all been glued/affixed in place with the pulley's off the Spyder and on the bench before being fitted. And AFAIK, all of these owners are still happy, at least so far?!
You want to give it a try?? Just don't tell anyone I told you...
