Hello, at 75 I've just bought my first ever cruiser - a Dragstar 650 Classic. AND I LOVE IT! But there is a feature I haven't seen, as yet, anywhere else. It appears to have two fuel filler caps, one on each side of the speedo. The actual filler is on the right. On the left, when I unscrew the cap, there is an identically sized hole but with a plastic reducer - making the hole seems too small to accept a fuel filler nozzle. What on earth is it doing there? It balances the look of the tank, I must say. But that can't be the reason. Can it? cheers
