My bike has a few more things then yours and its a 2000. I got it last year for 3600$ plus the guy gave me another 900$ worth of extra stuff, like beadlocks, stock rims, tires plastics , axle etc.... I sold all the extra stuff on ebay and got like 900-1000$
Banshees are a dime a dozen now thanks to the yfz450. Hell I bought an 89 in total pieces that needed to be put back together for 300$, turned around and sold all the parts for almost 2000$.
I say keep it and enjoy what you got
