What are the ups and downs of going with a different color than the stock red on the oversize tanks? I am considering an oversize tank (Clarke 4.3) and like the idea of sticking with the stock color, but I also like the idea of being able to see the fuel easier through the natural. The white tanks seem like they might get brown from rubbing. The natural tanks seem to turn brownish in color from the gas. Can you see the fuel level on the red tanks too? What are your opinions? Thanks.
