Cory, The only issue I have found is the location of the fill cap. With the Zega Pro top case on, I am only able to insert the gas station fill nozzle a certain way/angle and with that the tip of the nozzle barely clears the bottom of the filler threads without spurting a bit of fuel back out with the fill nozzle on full stream. With this issue, I am unable to determine when the tank is full to start slowing the stream down. For the automatic nozzle shutoff to kick in, the nozzle has to be inserted deep enough into the tank to work. Moving the fill point forward or aft on the tank in line with the seam won't resolve the issue. It would have to be moved outboard an inch or so to get the angle right for the nozzle clearance needed. The Zega Pro top case has a rapid trap feature so I can quickly lift and offset the top case for easier access. Im not sure how other top cases that are hard mounted will be affected though. Other than that one issue the fit and finish are perfect. I am paranoid though about the cap being lost due to not being tight enough since I don't want to crank it down too tight per the instructions. Can you advise if there is an over the counter auto part replacement fit that would work in a pinch if one of us is on a trip and looses the cap until we can get a replacement. That would suck DD to loose it in the middle of nowhere. Thanks for a great product. So far.
