yar itna tho market ma har ustad bike ki tuning ka baad check kartha ha,,
they rev it at full throttle for well 10-15 seconds,, i don't think just reeving hard alone for a small time is a way to kill motor,, he better remove all engine oil,, so it will definitely get hot to an extent that its parts will start to melt,,
cause u see ppl reeving their bikes at top speed on roads and still they dont get killed,,
