Complete Jet Kit for CSC Motorcycles TT250 & SG250
If you want to optimize the performance of your TT250 or SG250 carburetor, this jet kit is for you.
The stock main jet size is #108, which works well for most situations. However, you may need to adjust the main jet size depending on factors such as altitude, temperature, air intake, and exhaust system. The jet kit includes two additional main jets: #112 and #115. These are larger than the stock main jet and allow more fuel to flow into the engine. This results in a richer mixture, which means more fuel and less air. A richer mixture can increase the power and performance of your motorcycle. However, a richer mixture can also reduce the fuel economy and increase the emissions of your motorcycle. It can also cause problems such as fouling the spark plugs, overheating the engine, or backfiring.
CSC Motorcycles recommends researching how to properly tune a carburetor before installing this kit.
The jet kit comes with:
- #112 Main Jet: This jet is slightly larger than the stock main jet and can improve the performance of your motorcycle at low to mid-range RPMs. It is suitable for mild climates and altitudes below 3000 feet.
- #115 Main Jet: This jet is significantly larger than the stock main jet and can boost the power of your motorcycle at high RPMs. It is suitable for cold climates and altitudes above 3000 feet.
- #40 Idle Jet: This jet controls the fuel flow at idle and low RPMs. It can help you achieve a smooth and stable idle speed and prevent stalling or hesitation when you open the throttle.
- Air Mixture Screw: This screw allows you to adjust the amount of air that mixes with the fuel at idle and low RPMs. You can turn it clockwise to make the mixture leaner or counterclockwise to make it richer. A leaner mixture can improve fuel economy and emissions, while a richer mixture can improve throttle response and performance.
To install the jet kit, you will need to remove, clean, and reassemble the carburetor. You can follow our step-by-step guide on our YouTube channel to learn how to do it yourself. You will also need to test and tune your carburetor after installing the new jets to find the optimal settings for your motorcycle.
With this jet kit, you can customize your carburetor to match your riding style and environment. You will enjoy a smoother, faster, and more responsive ride with your TT250 or SG250 motorcycle. Order yours today!
