I own an 04 600rr, 17xxxkms.. I only aquired it recently & am not sure about a few things...
Firstly, sometimes on a cold startup, I can hear this loud knocking noise coming from the engine. It only last for 3-4 seconds then it sounds "normal". When I did my first oil change (using motul 5100), I didn't fill to the max level on the sight glass, it was slightly above the lower mark. I started the bike & it made the same knocking noise, but it didn't go away for approx 20 seconds, so I hit the kill switch, topped up the oil & tried again, which seemed to work... no knocking noise..
I this normal? or should I panic?
Also, when I'm cruising at low rpm, If I throttle on firmly, I can hear a clunking noise.. It's really annoying, I have to be dead smooth or else I can hear it, note: it's definitely not from the chain being loose.
Any help would be appreciated.
