Hi everyone. I'm new here and kind of short on time as i have tests to study for, but I just couldn't help myself. So I will just get right to the point. I was wondering whether a 3HP Briggs & Stratton motor would be better or the conventional 80cc/66c ebay bike motors? I'm pretty sure the 3HP Briggs will fit in a scwhinn stingray occ. I attached some pictures. Thanks in advance
