    70 might be limted if you havent got right exhaust to match it. i.e malossi mhr rep with leo vince tt exhaust is not going to kick out alot of power, cant rev high enough to reach peak power.

    my mates speedfight has upjetted to a bigger jet , lighter rollers 7g and leovince exhaust , and i have a 17.5 carb , 5 gram rollers polini sport 70cc cylinder and a technigas exhaust. mine used to wheelie off the spot but now reaches the same top speed near enough but a lot slower , gets to 60 kmh slow , then it feels like the power kicks in and shoots off
