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.

Why does my power band in my ktm 65 not work properly?

If your power band in your KTM 65 isn't functioning properly, it could be due to several factors. A common issue is a dirty or clogged power valve, which can prevent it from opening and closing as intended. Additionally, check the carburetor for tuning issues, as improper jetting can affect performance. Lastly, ensure that the exhaust system is not restricted, as this can also impact the power band's effectiveness.

Proper jetting for a 2005 KTM 525 exc?

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.

What is the correct fuel mix ratio for a 2007 KTM 125 motorcycle?

IMO, Ratio depends on the carb jetting and oil quality. Try 32:1 (gas:oil) using good synthetic or syn-blend then jet the carb. With stock jetting that should be in the ballpark. Higher altitudes will require leaner jetting (smaller jet size not different gas:oil ratio).
