Should I trade a 2005 yamaha warrior(1670cc) for a harley?

Have my stock warrior with 12000 miles up for trade on craigslist. Would like to get a big Harley for it. The downfall of a warrior is my friends have big Harleys and the warrior gets rather hot to the and legs when you drive in town. Very fast and dependable though. Should I trade and what should I expect to get for it. Blue book is $8000 and that's what I paid for it one year ago. Any advice?
