I think adding 2 stroke oil into the gasoline will only increase the amount of oil in the cylinder. This will cause poor running. The spark plugs will eventually foul, (will not spark). The oil must be stopped by replacing whatever is leaking: piston rings, guide seals, cam assembly gaskets, or cylinder head gasket.
I am sorry if my confusion and question confused you. At first I did not see that you are not a native English speaker. Technical things sometimes do not translate well.
If you have a compression tester, or can borrow one, the piston rings can be checked by first measuring all the cylinders for compression with the engine cold. Check them one at a time. Then add a small amount of oil to each, and test again. If the compression value increases over the first test, you may need to renew the rings and hone the cylinder walls. This is usually only needed on high mileage (Kilometers) bikes. (Or one that has been used heavily).
Gaskets and seals can only be fixed by replacing them.
Best of luck and I hope it is an easy fix for you.
