You didn't buy it to sell it, you bought it to use it so you have less into it than a Honda or Yamaha.
Yeah, you most likely will have to reduce your price, add in "negotiable" and be willing to deal a bit..
I instantly ignore any ad which states "FIRM" because when I am looking to buy used I AM looking for a deal and buying used does have great possibilities of buying the sellers JUNKER..
If you have a place in front of your home that you could set it out close to the curb you could set it out with a for sale sign. That is how I sold a old 2000w Sportsman open frame gen I wasn't using.. I did only get half of what I paid new and that gen had less than 10 hrs of use.. But hey, I got it cheap at a mere $150 and sold it for $75..
