Used boondocker liquid nitrious setup. It is a 4lb carbon bottle, along with the unversal fitings to fit any carbed snowmobile/atv etc. It is a complete, working setup, but there are two fitings missing going in, and out of the solenoid. Most major hardware stores carry them, i have just had no use for it. Price is somewhat flexible, but would like to stay within reason. Call/text for more information.
