just check the venders, piston bikes, gass bikes, piratecyceles, just naming some, you can find them right here on the forum on the left side of the page, i got mine from piston bikes but i know the rest have them too!, (i am not a vender or a seller, i am sugesting where too look for tanks for standerd 2 stroke bike kits.) (feel free to take this down if it violates eny rules, and if it does sorry, i am new to this and dont quite understand the rules, haha, sorry.)
