Re: gas tank on rear rack..
Yeah it does look less like a motorcycle with the tank in back. Most people don't even notice the engine on my bike until I point it out.
lilffihn- I responded to your PM with specifics. Extra fuel line is nice to have around. ACO sells 2 ft of 1/4 clear fuel line for $2.50. Depending on what you have around (wallmart/HD/Lowes), check out the mower section as most if it is probably on clearance right now. In addition to fuel line, you could probably find good prices on 1/4 shut offs or 1/4 inline filters. Might as well grab a bag of small hose clamps as well just to be safe.
