My top front, and very back bolts on my bash plate were beginning to strip out, so I drilled all the mounting points out, tapped them, and went to bigger hardware, and now it fits very tight and snug. My first drive out, I kept hearing this "whirring" sound on and off...stop...get off bike...listen...nothing...get on bike...it's back...get off bike...go to other side...listen...nothing...back on bike...it's back....lol...
It onlt started since I fixed up the bash plate, so I can only figure it's something to do with that (Sound reflection/harmonics...)
X2 on the exhust as a possibility as well though. Mine with a megabomb/Ti PowerCore combo without the spark arrestor makes a crazy "klacking" sound at low RPM...sounds like a license plate slapping in it's mount with vibration....put in spark arrester, and it's gone....
These engines seem to make some pretty funky noises as a rule of thumb compared to other engines.

I finally found it. It is the rubber seal for the speedo!cleaned an lubed squeek is now gone.
We have a winner.
Mine did the same thing, little grease under the rubber cap where it rotates on the hub and no more whine.
