my first suggestion would be to move someplace warmer, then worry about the noise LOLUpdate: Cold as all get out today, but took her out for about 5 hours anyway. How cold was it? At 65mph the engine temp was 162...
Did the turn-off thing and the pull the clutch in thing. No difference. I was just too darn cold when I got back to lift the front end and spin the wheel, but that's OK, because I noticed something important today.
My backroads roaming took me over varying types of pavement. There were a couple types of surfaces, where when I hit them, the noise stopped! It didn't fade out or anything, it simply stopped on a particular surface and then started again the moment I changed surfaces.
The normal asphalt in this area is very pebbly, even on the highways. It's when I went onto a visibly smooth surface the noise ended.
I'm still not sure it's tire noise alone. I think what may be happening is the road surface is setting up a high-speed vibration in the plastic fairing. This equates audibly to the mid-pitch hollow tone I've been worried about.
It should be warmer on my next day off on Thursday. I hope to strip her naked and take her out. I'll let ya'll know what happens.
