Help! GZ250 Gear Box Noises

[Shawnski451]

I've put around 500 miles on my GZ250 since putting it on the road and one thing that I've noticed is that the gear box seems to make quite a bit of noise (whine) when cruising and even louder when under power and all but goes away when coasting or light throttle. Is this normal for it to make this noise? Just getting paranoid and want some confirmation. Thanks!
