My woo,woo,woo,woo sound was something entirely different. I found that the shop that changed my rear tire, did not properly reinstall my drive sprocket. It was not oriented back in the original position it came off, and the bolts were not torqued correctly. I pulled it off, cleaned up both mating surfaces, repositioned, and torqued, no more woo,woo. Worth a try.
Interesting. I put a PM wheel on from Coastal Moto that came with the ME880 mounted. I installed the sprocket myself & it's on right. Going straight, silent, lean left or right, woo, woo, woo. It's got to be the tires. I just ignore it now.

Yep... I don't do well with keeping up with tire pressure or bolts.

I had a noisy rear tire on my 2010 RKC after 7k miles. The tire was cupped pretty badly even though I kept the tire pressures up to standard. It was very loud.
The tire still had reasonably good tread so I experimented with belt sanding the edges of the tires to knock off the high spots. Figured I had nothing to loose because I would have to replace the tire anyway if it didn't work.
It turned out to work really well. Almost completely eliminated the noise and I got another 3,000 miles out of the tire before the wear bars began to show. Here's a picture I took while doing the belt sanding.

My Heritage (RIP) had the original dunlops that didnt whooooooooo and replacement ME880's didnt either. Not to beat a DH but I am experiencing a harmonic whoooooooo and not a humm, though it seems hands down tires just wanna be sure I should not be looking elsewhere on the bike.
Belt sander, nice idea!
