Before I go through the trouble of removing the seat/gas tank of my ZR500, I was wondering if anybody knew if the flat plastic peice under the actual seat held gas of if it was solid plastic or what. I have looked at the microfiche for it and nothing tells me. I have a seat design that mounts to the tunnel that I really like that would look slick on this sled but it would require me to cut off all the plastic that isnt part of the main "gas tank". anybody know anything about this or have seen this done? thanks.
