Re: G1 big bore kits??
They also make dirt bikes with an even bigger bore, no cooling fan and fins often covered in mud ? P.S. In 2016 when I built Suzi with the 440 FC snowmobile engine capped off with a HD cart muffler some naysayers predicted over heating and fried pistons and rings. So far even running her hard on 90 + degrees days it hasn't happened.
