How does the color on the fan cover match the color on the frame. It is a 1974 general motors bright orange. I also found a 1975 Volkswagen Fiesta orange that was close.
Could maybe try here to find any info http://www.cyclecolor.com/ID24.HTM Buell colors are listed at the very bottom of the page but there is a link near the top where you can contact them if you don't see "your color". Might help, worth a shot.
