hello i just purchased two pocket bikes. one is a small bike that i have no idea what brand and the other is a slightly larger agiano. i need help with gas to oil ratios and what type of oil and where to get it. and i need to know if there is any other lubricant that i need to apply to the engine before i try and run it because when you turn the wheel it sound like some metal on metal. right now i am focusing on the small bike most of it is minor fixes so far. the agiano was crashed so need a bit of work mostly body stuff though. i traded a remote control car for BOTH bikes so dont ***** at me for buying bikes i havent seen run yet. thanks alot.
