    I have ordered a stage 6 70cc kit, the one with more torque for wheelies.
    I have a better crank and main bearings going in.
    Motoforce variator clutch and clutch bell.
    Stiffer clutch springs.
    4.7 gram rollers i think
    And with a standard carb...
    Standard airbox with mallosi insert
    Gianlli extra chrome exhaust
    I live in lincolnshire and im unsure on jetting...
    Just a starting point would be amazing please help !!!!!

    when you jet start high and work your way down until it doesnt bog at full thottle. but run it a bit rich when running in the cylinder kit!!
