I have an 09 450,when the bike is hot it makes a weird sound high up in the engine .
I had a leak down test done thinking piston slap but the test gave good results.(at 90 hrs probably needs one anyway)
Cold the engine hardly makes a sound.
I have 90 hours on it ,a dirt tricks chain tensioner ,valve clearances ok .
It goes like a rocket its just un nerving when it rattles/knocks when hot.
any thoughts?
Regards GWP
