Hi, I'm new to dirt bikes. I was wondering about jetting. Someone told me that the numbers on the gold colored 'jets' inside the carb means the jets were lean or rich. If the number is bigger, does that make the jet richer or lener? I was guessing that the bigger the number, the richer the jet. Is that right?
