help with humming noise

After spending 1900.00 on a re-build of motor and trans(iwas figuring a tranny howl)
i still get this hum after the bike has ran a few miles.noise is according to speed and not rpm's.its not loud but annoying for sure.can it be a worn plastic shoe in primary case?
maybe a wheel bearing ?any help in getting this fixed would be boss!

RE: help with humming noise

I had a hum problem with a Gold Wing that I owned, and it turned out to be the vent was loose that allowed air past the fairing. It drove me crazy, and I tried unbelievable stunts while riding to try to hear where it came from. What type of bike do you have? Fairing, lowers, air deflectors, brake disk covers? Try looking at other things than the engine. It may be something stupid like a frayed speedo cable that is humming, and I can tell you from experiance that it is very difficult to hear the source of the annoying noise at speed.
