run across a lot of r's and that one looks very original and nice for the price. I know ar-15 vary a lot on price depending on condition. bike is well worth the 900. if your AR is worth more then need to negotiate some cash.
Nothing to worry about on the air cooled r's. they are pretty much bullet proof, ton of power and fun. if you are interested in a 2 stroke with a clutch go for it. you will not be let down
