Does it give you any more performace to change the main jet to a bigger one? If so which one would be good for a 20mm carb with a stock 139qmb?

more gas doesn't mean more power actually it could decrease the power run jets 79 to  max on a completely stock scoot i suggest an 80 or 82 with the 20mm carb |
