Hi boys,



Pleas help


My "new" Honda CBF 600 2008 resonates in motor.



time on video 2:20-2:50, best sound is 2:40


My Honda starts resonating cca 2 minutes after a cold start, and it takes about cca 30 seconds



Warm engine is ok..

I diagnostic with stethoscope this sound from oil relief valve.
In motor is new oil Motul 5100 ester 10w40 and filter Hiflofiltro 204.
Is problem this resonate oil relief valve or is normal?
Relief valve closing=rattle

Thanks
