That's the sound of mechanical pain when you load the engine at too low rpm.

Not sure I agree there, Deanohh. When I briskly roll the throttle on at 2500 revs in 4th or 5th gear it pulls as strongly as it does at higher rpms; it doesn't feel like the motor is anywhere near to 'lugging.' 1k or 1.5k rpm would be a different story I'm sure.
I only mention it as yesterday I was marvelling at how forcefully and smoothly the bike accelerates from 2.5k rpm in 4th gear.

Indeed the bike will do this but Deanoh is right, don't yank the thing open, roll it on very smoothly and you are good to go. Now is about the time to start talking about BMEP and the dangers of exceeding the maximum, I guess. If anyone is getting these noises under hard or brisk acceleration from low RPM in a high gear, ease off or downshift, that's all.
