Well, on my 79 maxi, when I installed a 70cc kit, it immediately had SO MUCH POWER! I broke it in for the 1st 300 mi at under 1/2 thotltle. It doesnt even accelerate with better power. And the machining quallity looks like garbage, the milling of the bottom of the cyl looks uneven causing a vaccum leak at the base.
