    US90 Larger Motor???

    My motor in my us90 is shot so I was wondering is there any larger engines like lifans that can be put in these things to make it go faster ad don't worry it wont have ballon tires the bike is just not worth it to restore so I'm going to customize!! So if anybody knows if i can put a bigger motor in this thing please let me know
    You guys probably are thinking I'm for doing this to a US90 but i want something different

    The chinese motors are all atc70 based for the frame mounts but can be modded to fit . If it were me I would find another atc90 or atc110 motor .

    I agree... a 110 motor gets you a little more power and CDI ignition. You may even be able to use a 125m motor, not sure if there would be clearance issues for the starter.
