So I’m curious about mini sprockets, almost all kids in my sons class which runs a 79cc predator, are running this mini sprockets. So a guy whose daughters is in the group says he’s on a 14/49 to a 14/52 mini set up. My son is currently on a 13/60 was going to try a 13/57 standard sprocket before we had carb issues and had to call it a day. My question is the performance variables between standard sprockets and mini’s, and I have 2 engines with brand new 13 tooth clutches I don’t really want to buy more clutches at the moment, where would be a starting point going to mini sprockets, that 57 range or possibly lower or higher due to the diameter difference?
