You can now list on ebay as a classified ad as opposed to a traditional auction. Great way to get national coverage for a set price and it's cheap. Selling fees are also cheap.
The brand is a strike against it, I hate to say it, it just doesn't have enough notariety to attract anyone other than the offroad knowledgable. Anybody that's new is going to be told by their buddies to get a jap bike or a KTM.
A 2-stroke is also a strike, the industry/sport has gone 4-stroke, like it or not that's the reality. Here in CA it's worse because of the red-sticker/greensticker issue.
A 3 year old bike, regardless of mods done (BTW,they don't add value) probably has a market value of half what the current one is selling for. I don't know what that is, but if it's $7000 then the used one is probly worth $3500, maybe a bit less to motivate someone to move on it. Expect to get an offer 10% lower than whatever you're advertising.
Motorcyle sales dropped some 80% between '08 and '10, virtually all models from '09 were still being sold into '10 and even still today. A friend of mine picked up a 2009 KTM 200XC last month, brand new on the floor, at not much less than regular price. They are also irreplaceble so dealers are holding at least some gross on them. That still doen't help the used market.
Frankly, I hate to be a naysayer, but the magic number is probaby in the low 3's to get a motivated buyer.
I doubt said anything you didn't already know. Sorry.
