We just picked up our new 500, and shame on me for not noticing, but it appears as though there's an excessive gap at the front of the seat where it meets the fuel tank. You can easily stick your fingers down into the gap. I can see where there are two tabs off of the back of the fuel tank that appear as though they should slide into the two receiving holes in the plastic seat substrate. There's enough of a gap that I can look through the gap, and actually see that the tabs are not engaging the slots in the substrate. When I pull up on the front of the seat, it doesn't come loose, so I'm not really sure what's holding it down. All I know is that it doesn't look right. Any suggestions?
