I'm looking t getting a bigger gas tank for the 4 stroke build I'm starting pretty soon. (getting the motor in February and the bike in April or May) I'm using an Electra beach cruiser for the bike and the 7G 4 stroke cause I'm on a budget. Now I saw it only had a 1.5 litter tank. Is there a good reputable seller that sells 1 gallon tanks? I wold like to build my own tank but welding tools are expensive.
