The whine never bothered me. It's not that loud or bothersome, maybe individual bikes have it louder than others, but mine it's not that big a deal. First gear whines the same way.
75-90 got rid of it in mine, I think, never really bothered me.
In the past I know it was there but I'm not sure if it's gone or I don't pay attention to it anymore.
Just a little when new in 07, after 10k or so has to listen for it to hear it..
Now with 28k and after switching to Mobil 1 75-90 GL can't hardly hear it at all..
yea they heard all the whiners, and now everybody with a 2010 and up has a helicut 5th gear which is WEAKER then the straight cut that used to be there.
