Hi.. my GS500E 1993 has oil leak, i have change the gasket but the leak is still there, does anyone can help me sort it out please?

You know what you mean by what you wrote, but the rest of us do not.

There are a LOT of places for oil to leak from. just saying "I have an oil leak and changing the gasket didn't help" doesn't clue us in on anything. WHERE is this leak - photos would help.
