here's what i said to someone else in your shoes: Keep it. The key is replacing parts that will dramatically alter the personality of the bike. I blew the engine on my 06...I was debating selling it for something new like the KTM RC8 or the s1000rr. I ride as much as I can to work and on the weekends; but honestly I just couldnt justify spending more money in a recession than i need to. So i decided to replace the engine and mod it with all the things I had held off on trying to be cost conscious. With a new exhaust, brakes, HID's, levers, sprocket, rearsets, and wheels its totally different bike. and for a fraction of the cost of buying a new one and doing the same mods.
