What jetting to run in a ktm 85 sx with a power pipe exhaust?

When tuning a KTM 85 SX with a power pipe exhaust, it's typically recommended to start with a main jet around 160-165 and adjust as necessary based on performance and conditions. The pilot jet might be best set around 45-48, depending on your riding style and altitude. Always monitor the spark plug color and engine performance to fine-tune your jetting for optimal power and throttle response. Remember to consider factors like temperature and humidity, as they can affect jetting needs.
