Engine noise

Hi have a noise from 6000 rpm on wards .
It’s not to far off a pinging sound . More when it’s a flat road and when the motors hot. On a hill or accel it goes away . Was thinking a cam chain tensioner or valve out of adjustment. It’s from that area on the motor . I’ve not checked the valve adj yet but I’ve turned the cam chain tensioner and still dose it . Any ideas ??

im no expert but i would check the valve clearances. that would sound more like a tapping though. how many miles are on the bike by the way? audible pinging like that could be detonation also.

Hi , it’s done 1800 kms , it’s defiantly not pre detonation . Just that similar rattling sorta sound . It might even be the vibrations from around 6000 rpm onwards of the plastic cam chain followers ?? Dunno
I will check the clearances and see .

These are vibey motors. Are you sure it's coming from the motor itself and not the plastics, clutch/throttle cables, mirrors, etc? Everything seems to rattle on these bikes.

Check the motor mounts. They frequently come loose. Blue loctite FTW.
