My favorite 500, my first one. In the beginning this poor bike was sporting a peanut tank that was painted with an old lady's doilie design stencil that wasn't may favorite. but it was the peanut tank that sat so high on the frame up past the handlebars and the coils and all those wires that were showing that really bothered me so I changed it to this mustang tank and always liked it . During the last paint, when I upgraded the engine to a 550 just because , the tank sported ghost flames, it was cool then, but recently I thought that I might like them better outlined in black like old school. I've been liking it much better that way , and feel even better about taking my fave 500 with a fresh 550 in it out for a ride. I wonder if I should start looking for a 650 engine for the next time it needs freshening.
