On my F650GS twin today I noticed on both sides of the fuel tank just under the body color panel the plastic has separated and formed a 1/16" crack for several inches. You have to look close as it is in the molded 90 degree indentation that runs along each side. I didn't think a photo could be taken that would show it so the description is the best I can do. The fuel tank must be doubled lined or something or gas would be leaking. Or maybe this really isn't part of the fuel tank but I will show it to the dealer when I go in for the 600 mile checkup. I have about 750 miles on it and I'm more than a little concerned. Let me know if you see anything similar. Thanks.
