Getting my cart back out this weekend. 1990 Ezgo Marathon with stock 3PG. Other than adjusting the governor what can I do to get a little more speed out of it? Considering a lift kit this year for taller tires. Should I change the air filter setup? Exhaust? Figured the OEM carb was probably better than most aftermarket ones, should I swap that out? Anything to be done with the clutches? I don't know much, just enough to keep it going every year. Those predator engine swaps look fun but beyond my expertise and seem less reliable.
