    and has for tuning it , change the exhaust for a sports one , up-jet the carburetor to match , and you can always play with sprocket sizes to increase acceleration or top-end

    What year? its probably a minarelli am6 which means very very tuneable.

    And yeah, standard restrictions are exhaust washer, cdi and sprockets. 2 more teeth on the front sprocket is always good.

    If its an am6, 70cc top ends are really easy to find and will give great power. Its worth bearing in mind that these engines need stronger clutch springs with any decent increase in power.

    Shame really, my mate has a morini engined h@k with a 19mm carb, italkit 74cc kit and gianelli pipe along with other mods, it fucking hauls for a 70! Much faster then any other tuned ped i've been on, including (only just) my mid race aerox.

    Once geared bikes are tuned they can be great fun, much better top speed than TAG's too

    New exhaust and upjet, and bigger front sprocket.

    You could just derestrict the standard exhaust but it wont be as good as a performance one.
