I have never sold a bike, except to family or friends, so my experience is null. However, in central Illinois in November?? Starting just before the holiday shopping time? I think what you're experiencing is what should be expected. Take it off the market until at least until March, then raise the price $500-$1000. While you are waiting, remove and sell farkles here or on ebay. I just drove through central Illinois a couple days after Christmas, when I left Chicago it was -2 F, by the time I got out of the heat island effect of the city and down around Bloomington it was -16 F! Not when most (if any) are shopping for a motorcycle.
Best wishes for a sale.
