i really dont know how much they are worth, i see running 2000's going for like 1000 to 1200 so i would say like 500 or best offer. i didnt pay that much for it and i dont have any use for it so as long as i get a little more than i payed i will be happy. the engine needs a new crank, seals, piston, and some other stuff, im not sure if all the bolts and clips are there for the engine. i have the engine mounts though. it would be better to buy a used engine for it. i have the pipem carb, etc too. so all it needs is the actual engine and your ready to go. i think it is geared towards 8 to 12 year olds. i dont have any paperwork on it, i bought it from a repo lot, they were messing around on it and blew the engine, so i got it very cheap. if you dont like my price, just make me an offer!
