Hey all, im pretty new to dirt bikes and ive heard a lot about the value of rejetting you carbeurator when you ride in different conditions. Ive heard that you can regain loss horsepower and torque by just adjusting pins and needles. My dad on the other hand is kind of skeptical about the jetting routine- buying jetting kits and having the hassel of picking a right combination of needles. I have an ATV and I live in Arizona, we ride a lot at my granparents house in NM which has a much higher elevation and different climate than down here in the valley...I guess I'm trying to ask u guys to explain the benefits of rejetting my ATV and regaining some of that lost horsepower. Any replies are appreciated. Thnx a lot guys-Kyle
