Also, I know this may sound barbaric but I need to know about something lol. My motor that I want to use is a Honda GX390, now the Kart came with motor mounts that allow multiple mounting locations, but being such a large engine, it is too wide for it to sit on the mounts and fit between the tire and the seat including the shaft lenght. If the Shaft wasnt so long Id have no issues with it mounting.... Is there a way to shorten the shaft? Can i just cut it? like maybe a machine shop use a band saw? or me with my sawzall??? lol, I mean, Id like for this thing to go fast, but Id like to be able to sit on it too lol....
