The reason for selling is because I put my bike in my old mans name so I could get cheaper insurance rates and he said if I ran the nitrous he wouldn't let me stay on his insurence plan soooo I have to sell it, and if I don't sell it, its just gunna sit around, and zr you should have gotten an email it was tittled z1000 nitrous kit, check ur spam box, I sent it from my blackberry
