I'm looking for opinions if I should re-jet my bike. It's an 01 KDX 220 with a Pro Circuit pipe and silencer. I've only had the bike two weeks so last night I pulled the carb to see how it's jetted. I found a 160 main with a 60 pilot. After reading the tech section on this site it looks like others run smaller jets (42 pilot, 145/148 main) My plug color is perfect so should I bother changing the jets?
