I know you guys are good at explaining the Suzuki oil leak, but someone on here the other day asked about oil on the fins. I have been riding all summer with a leak on the fins. Just hosed it off with degreaser. Got bad like it did last year, so I just came inside to write this. It was the nut on the front of the jug/head seam, again. It was about 1/4 turn loose, just like last year. Hope it stops again. Always check simple stuff first.
