Gasket?

I finally finished my bike yesterday, it's looks good and started right up. I let it idle for about 5 minutes and oil started to drip out of what it seem to be the front sprocket. So I shut it off and pulled the bodywork off so I could see it alittle better. Started it again, oil starts to leak. It's not coming from the F. sprocket, but from the lifter rod area between the F. sprocket cover and the engine case. So i was wondering if there is a gasker that goes between those two spaces? Thanks

Lifter rod?? Engine Case?? Sound expensive ...is it engine oil or brake fluid? If it's brake then your slave cylinder has a leak some how but if it's oil then ....holly molly $$$$$$$$$$$$$$$$$

It's motor oil. I just put the motor back together, everything looked great. I cleaned everything off yesterday and there is no cracks or anything, thats why I asked if a gasket goes there.
