It only seems to knock under load. Starting in first gear the knock would be very drastic. Switching to 2nd gear at around 3500 rpm there would be a light knock but only for very short period of time. While in motion with the higher gears it would not knock when i'm gradually giving it throttle. But if i throttle it a bit aggressively it would knock.
