Can you guys have a listen to this please and see what you think? It does sound worse on the video though.

does it go away with a bit of revs or when you pull the clutch ? if so, learn to except it

Its definitely NOT the crank,if it was a main bearing on its way out you would feel vibration through the bars and pegs when revving it,if it was the big end well they normally just let go through oil starvation.
Still sounds like its coming from the clutch area,got decent/enough gear oil?
be worth taking the cover off and checking the clutch.

manual says standard 10W40, but off course bike-engine-oil and not car-oilLuders wrote:It needs to be gear oil or dexron. You have a wet clutch which is reliant on the oil. Standard motor oil will knacker your clutch friction plates..
I just put ATF in mine.

Have a look at the gear that is on the back of the clutch basket and associated gears and check that none of the teeth are chipped,
When my lc engine was rebuilt it had this and the top edge of the teeth should be flat (not sure on a kr) but three of them in a row were pointy and two had very small chips, it sounded like the engine was knackered
Something is making that noise,
Just a thought,

Hi Folks
my KR sounds as if i had a dry clutch.
especially with the engine cold.
I think always the engine is broken.
what the heck ... it's a KR!
i use Motul Transoil Expert.
regards
