Hi! Tried really hard to listen and hear the noise you described, but couldn't detect it. Sorry! Could be a number of things, but if the bike runs ok and the oil level is correct then I'd try and ignore it or if you are really troubled by it, take it in to your friendly dealer for an opinion? I hear some stranges rumbling sounds when I ride my Honda CBR 600 F1, but I try not to let it bother me as the bike runs just fine. Probably amplification through the fairing of the tyres on the road, but not sure. Let us know how you get on and a second opinion might dispel your fears! Have the valve clearances been checked/adjusted for a while? The cams could be the culprits if the clearances are too wide. Just an afterthought.

 

Thanks for the reply, to make the noise much louder, I have remake the video,, plz check again. many thanks !

Thanks for making the effort to produce another video, but I'm sorry to say there doesn't seem to be any unusual noises coming from your engine that I could detect. It is difficult to diagnose from the video as I hope you will appreciate. Being on 'old' biker, I've never taken my CBR up to the kind of revs you do on your bike, so I can't comment on what noises would be produces at so high revs. One thing that has crossed my mind it for you to check the front and rear brake pads to see if there are any problems there? Wish I could be of more help.

 

Thank you for the kindly reply, I'll check it later and see whats going wrong if the noise get worst.

 

I have to agree. The sounds seem to be normal bike sounds. Maybe a little noise from the front sprocket or chain maybe, but nothing outrageous.

 

if you have high rev noises ck oil levels but honda cbrs tend to sound alittle clangy at high rrs--i road race so mine is at 10k plus all the time and all kinds off sounds come out. best thing is determine the sound and see if it gets louder or changes pitch then you mite have an issue otherwise ride away.mine just keeps on going
