Engine buzz under load?

No. Chains sound like this maxima. You can hear it most as the engine rpm is coming down after the throttle snap. A whine.

In his case the plastic the chain rubs against is worn or broken off the tensioner and is now on the metal so is louder than normal. Our yarii chains are a little noisy but seems normal.
Cheers.

so what am I hearing then...mine sounds much like in the link I posted, except that I have to be accelerating, not just revving.

EDIT: although I must say that the noises in these 2 videos are not that far apart tone wise, esp accounting for the variations of the recording equipment/environment
