The chain and sproket are a bit worn but can go a few miles. Will change that firste before stripping the case. Thanks alot people

No it remained the same. The noise is heard even at 120KM/h. Oil is fine. It does get louder when going throught the gears exspecially from 3rd up. When driving and i close the trotle a bit it shuts up but when opening the noise starts again.

Replacing the bearing on the sproket shaft.

i have a Fzr1000 Exup. Makes a noise when under load. The chain was tight when bought. Can i remove bearing without poping pistons and rings?
