Is it worth it to upgrade from a 14 mm carb to a 15? I have a 70cc kit installed already and am reaching about 40-42 max. I also have a performance techno exhaust and my gearing is 16/40 (to make sure the RPMs don’t get too high). And if I upgrade to a bigger carb, do I have to use a new jet? (I have a 76 in right now, which seems to be working the best). And would I have to readjust the timing of the stator?
Sorry for the ton of questions, I’m trying to find a solution for better low end power and maybe a few mph faster at top speed.
