I'm in 2 minds about my tanks. I love the way they look on the bike and I love the extra range.....
In the hot Australian summer I've been stranded for days waiting for the tank to come into shape enough to remount, I've had continuous fuel leaks from around the fuel pump. I've had several gaskets fail and the top mount on my bike is broken/bent from the expansion. I've had all these issues with the fuel pump side not the other. Im sure its a problem with that particular side. Deaf ears at Safari tanks though, they just send more gaskets to fix the leak and they disintegrate within weeks. I've cut a cork gasket and that's working nicely.
For the price you pay for these things I just expected a little more.
