The gear change has to be absolutely to spec, otherwise - humming noise. Is it a higher-pitched hum or lower-pitched hum? Is it constant or does it change when cornering? Does it change under load? Does it disappear when depressing the clutch at speed?

It's a low pitch hum, and goes away with throttle off, but continueious while using throttle, I to had my gears changed and that's when it first started
Sounds like the mechanic didn't set the backlash correct.
