I believe Forest is talking about a CA. Swapping gear is not necessary, the stock gear ratios for 2nd and 3rd are different from the CB.By the way, if you ever do have your transmission opened up, I suggest you look into Xing 2nd and 3rd gears, which gives a more even spacing. Many prefer moving 2nd closer to 1st, and increasing the gap between 3rd and 4th gear ratios.
