Hello guys ! 

 

My bike start to have some hours and i notice last time i went riding i saw some oil leaking a bit from the top engine bolt (see the picture). 

 

Should i just unscew it and replace the copper ring, isn't that a bolt to drain excess oil ? If it is why is it leaking even if did not put not too much oil.

Those have sealing washers   Pull it out and replace or try to tighten

That's an access bolt for the rocker arm shafts. Strange that it is leaking but you can just take it out and put a new sealing washer on.

No oil up that high except when running.
