** A new open-box item in its original packaging.**

**14-Tooth Clutch Specifications:** This go-kart clutch features 14 teeth, a 1-inch bore, and is compatible with 40-41-420 chains. It supports engines up to 6.5 horsepower and operates at speeds up to 2300 RPM. Please note that the chain is not included. Prior to initial use, apply lubricating oil. After installation, perform 3-5 break-in cycles.

**Broad Compatibility:** This 14-tooth centrifugal clutch is designed for engines with a straight shaft ranging from 2 to 6.5 horsepower, operating at speeds up to 2300 RPM. It is suitable for various applications, including mini bikes, generators, garden tractors, go-karts, scooterx sport karts, mini choppers, and mini motorcycle engines.

**Usage Tip 1: Lubrication:** Before operating the product, we recommend applying lubricating oil above the retaining ring, ensuring full saturation. Allow the oil to seep in, then rotate the clutch. If rotation is smooth and unobstructed, disassembly is not required. (Refer to the image below for the oil application point.)

**Usage Tip 2: Break-in Procedure:** Upon initial installation and operation, a break-in period of 3 to 5 cycles is necessary. This prevents issues such as insufficient contact area of internal clutch components due to inadequate speed, which can lead to slippage and friction-induced smoke. The recommended break-in steps are as follows: First, run the engine at no-load until the clutch engages for the first time. Maintain engagement for 10 seconds, then shut down the engine for cooling. Second, gradually increase the load three times, from 0 to full speed, allowing a 2-minute cooling interval after each cycle. If no issues arise during this process, normal operation can commence.

**Why Choose YOUXMOTO:** Our go-kart clutches are constructed from high-quality iron, ensuring robustness, durability, maximum torque, wear resistance, and efficient heat dissipation.

**Important Considerations:** This 1-inch bore, 14-tooth go-kart clutch is specifically designed for single-wheel drive karts with tires no larger than 15 inches in height. The chain is not included.
