Nope, it should be coming from a little plug or a couple of loose bolts. The upper head "gasket" is either high heat gray or high heat copper, "tube of goo" sourced. Replace the little rubber plug, clean and regoop the upper head to lower head mating surface. No gasket needed, that's why Permatex makes gray gunk.
Mine has leaked since it was new, so have the fork seals. I just hose the mess off occasionally. You should see the underside of my bike, if it can leak, it does...
