What is this noise?

[slatroni]

When I start the bike it sounds fine. When I put it in gear and take off, there is a zzzzzzZZZZZZZ noize. It follows the RPM and gets louder under a load. It sounds like it is coming from the left side of the motor.
Thanks for any help

chain noise perhaps?

He is describing the very sound you hear from EBC HH brake pads, but I dont know what he is hearing.

Chain noise I'd say

If you can hear the zzzzzz sound over the sound of your exhaust, then its something serious. The only thing I hear from my bike is the HH brake pads but they dont make a zzzzz noise. Id take the rear wheel off first and check your bearings, then lube the axle. Then front wheel. Troubleshooting...
