A high-quality O-ring gasket is utilized to minimize leaks and ensure the carburetor's seal integrity. The needle jet kit is made of brass to provide better wear resistance than traditional needle kits, while the main jet is constructed using tungsten-carbide needle. The Mikuni TMX38-59 carburetor is designed to withstand the rigors of aggressive motocross riding while maintaining optimal performance.

Installing the Mikuni TMX38-59 carburetor on a Yamaha YZ125 or YZ125X is a straightforward process. The assembly comes with detailed instructions, ensuring a hassle-free setup.
