Engine knocking noise at 4000-4500 RPM only Fazer 600

Hahaha of course not, the engine is off.
I also did that, no stiff link.


do I need to drain the oil before opening the clutch cover if the bike is on its side stand?


I also think there is excess oil in the bike. the window is completely full.

The chain looks very tight, and once loosened to the correct movement you really have to make sure very gradually that the wheel is straight once tightened back up If you spin the wheel backwards on the centre stand it should purr very smoothly with no clunking or biting noises from the chain. The two combined if incorrect, which is likely i reckon, could cause problems mentioned, or at least be a part of it.


You can lean the bike on the side stand only to take the clutch cover off, but do not even think about putting the bike upright for any reason once it's off And take the engine out of neutral before doing it.


(for just a standard oil level check) ON THE CENTRE STAND on a flat surface, start the bike up and let it tick over for at least 1 minute, switch the engine off and give it another minute to settle, THEN check the oil level.
If you cannot see any level there's either too much oil, which is bad, and the oil maybe old too, or another possibility is that your window is dirty and blackened out. I had my window replaced late last year while the bike was apart as i couldn't see anything for quite a while. But start the bike and do as mentioned, because it may be okay.
