Proper jetting for a 2005 KTM 525 exc?

Answer 1

To achieve proper jetting for a 2005 KTM 525 EXC, you should start with the stock jetting as a baseline, which typically includes a 165 main jet, a 42 pilot jet, and a needle positioned in the middle clip. Adjustments may be necessary based on elevation, temperature, and modifications to the exhaust or air intake. It's crucial to check the spark plug color after riding to ensure optimal fuel mixture, aiming for a light tan color. Fine-tuning may involve moving the needle clip or changing jets to achieve the best performance and throttle response.
