We talk about mopeds where, ya know, older motorized bikes with pedals and large wheels (16 or 17 inch). Most of us know nothing about scooters and very few of us are highly technical tuners with a broad range of knowledge.
Is that a 2 cycle motor? Reed valve case inducted? You might get a performance boost with using a turbo but would think that hitting 75mph is FAST ENOUGH on such a small scooter!
If it is 2 stroke, RUN AN EXPANSION CHAMBER EXHAUST STAT!!!!
