Daytona955i

Got back from a spirited ride on the Dayto and noticed a strange smell as I was putting it away - it was dripping oil onto the exhaust on the right hand side. Today I took a look and the gasket was in good shape so I just put some gasket silicon on both sides of the gasket and torqued the cover into place and hopfully it will be alright. I put the same oil back in as it has only done 5K kms. There is one cover bolt that has a washer on it for no apparent reason I neeed to find out where that goes....
