Oil Leak

Hi Guys,

I have got an oil leak on my Engine and silicon cant seem to sort the issue.

What do I need to replace? The top gasket only ?

Also when I rev the bike hard, I can see smoke from the exhaust. What should I check for here?

Kind Regards

top gasket, also clean off fully and make sure no oil is coming from the decompressor plug. Smoking just on start up will be valve stem oil seals, smoking all the time piston ring's or maybe a re bore of you are unlucky.
