As title says ive recently noicted a fast rattling/vibration coming from the engine when i accerate hard. Begins at about 8,000 RPM onwards. Doesnt realli bother me much as you cnt hear it when viser of helmet is down, but when its up you can.

Is it the engine mounts?

If the engine sounds sweet, i'd look at loose bolts.
