    Hi guys!

    Thanks in advance for the help! I have a Yamaha Gear. It has the same engine as the Giggle/C3/Vox (xf50). So the engine is fuel injected. I would like to use a 60cc cylinder, but I wondered, should I use a different fuel regulator as well? Mainly, because with the bigger cylinder, (which is about 20% bigger) more air will be sucked into the engine, right? So will the mixture be too lean? Or how the ecu will compensate?
