i own a 2003 z400 i bought it i believe 3 years ago this december i am the second owner and the guy who owned it before me treating it almost as good as me. I put a set of nerf bars a full yoshi exhaust a set of hadlebars, handgurads and even a speed for all the trail riding i do. i also put full skid plates on it a durablue +2 axle and a set of brand new holeshot HD's with less that 25 dirt miles on them they look brand new. I took amazing car of this bike it was garage kept and kept under a cover i washed it everysingle time its seen dirt or anykind of road and you can tell by how clean it is. It was also waxed everytime it was ridden to keep the plastics from fading. What is a good price to ask for the bike i know aftermarket parts dont increase the value of this bike but i live in Moorestown New Jersey where people have extemely large amounts of money. I am not in a rush to sell it because i want to hopefully sell it and buy my streetbike by the spring is $5,000obo asking too much for just about a mint condition 03 Z400 with 3k aftermarket parts into it in the Best Town In America (i dont mean to brag i cannot stand 99% of the people who live in this town.)

 

id say thats a fair price, rich people will buy anything

 

I think it all depends on where you live on how much you get for it. back east I think $4500/5000
here in phoenix maybe $4000/4500 IMO
