On my C650GT, there is a leak at the seam between the two pieces that form the case of the final drive.

After about 100 miles, I noticed oil drops on the garage floor and the underneath side of the final drive was oily.

I took it back to the dealer and the mechanic tightened the bottom bolts; he told me four of them were really loose.

Not more oil drops on the floor, but still some oil seeping out all around, top and bottom.

Anyone else has seen this?
