I have the trx 2.5 engine and a 72 tooth spare gear should i use 6 pegs or 12. It has 12 in at the minute but i just bought a new one with 6 pegs in. Also the one i swapped had 6 pegs in but i read that 12 is better so i put 12 in. Have i done the right thing what would be the difference in performance if any?
