November 30, 200817 yr Hi, when i fill my fuel tank with fuel & then bounce the bike around it seems to be escaping from the bottom part of the filler cap & quite a lot of fuel leaks, the cap is very tight though & it's getting a bit annoying now though Cheers Ben.

Ben, Check the gasket for a good seal and you usually can adjust the sealing pressure by tightening the small nut on the inside of the filler cap. Jon
December 1, 200817 yr I had a similar problem on my 08 250. The ID of the tank opening was about 0.050" undersize and wasnt finished machined (rough edge on top ID surface) - no anodizing either. The cap would barely fit into the tank and the seal would leak at the back edge. My dealer swapped out the tank and now its fine. If its not a simple tension adjustment like JSE suggested, it may be possible there is another few bad tanks floating around. You may want to compare it with another GG to see how they should look and measure.
December 2, 200817 yr Author i have tried adjusting the tension of the cap but it hasn't worked the leak is coming from the part that you lift up to get the cap open, leaking out of the bottom of it
