So I did the yosh rs-2 full system, the 3x3 mod and the JD jet kit and the bike runs great. Only problem is that my buddy's 01 DRZ-S runs neck and neck with me. He has only the pro-circuit full system with no jetting or other mods, 14,000 miles on it too! The only difference is that i'm running my stock SM gearing and he has 15/47 on his. Any ideas? Should I change gearing?
