Mine was set-up this way... then I did some long-slow climbs on a hot day. The exhaust hitting the gas tank heated it up enough to cause some MAJOR expansion in the tank. On a steep incline, gas was being blown past the cap seal and when I got it leveled out and the gas in the filler tube drained back into the tank, I loosened the cap a little bit and it hissed at me for about five seconds
assgas: .
Needless to say, before I took it out again, I had the pipe run back out to the stock location. I can deal with a little rubbing on the tank skid and springs as long as my gas isn't simmering.
