No, that would be to easy.. Faito 148cc, cardinals racing big valve head. Head ported, kitaco valve springs, daytona cdi, mikuni vm26, takegawa exhaust and faito stage 2 cam. It wil do a litle bit more whit the timing chain on time, and whit a yoshimura yd28 i think..
And yes you can easy crouse @100km/h
Actually 125km/h is nothing.. I see innovas running on youtube @ 185km/h like its nothing
