I have a 2003 XT600E, and covered 30,000 relatively trouble free miles. Recently I have noticed an oil leak coming from around the starter motor area. You can actaully see it running down from under the starter on the back of the left hand crank case. Is there an oil seal or gasket that could be leaking between the starter and the crank case? I haven't stripped anything down yet, I thought I'd ask some advice first!!

There is usually an "O" ring fitted around the end of the starter motor where it goes into the crankcase.
