The carburetor repair kit N090-068 contains a fuel line, a fuel filter, a Bakelite gasket, and a paper gasket. Universal motorcycle maintenance parts.

This product is a basic accessory kit from GOOFIT, specifically designed for carburetor repair and maintenance (part number N090-068). It is not the carburetor itself, but a set of essential wear parts that need to be checked or replaced during carburetor disassembly, cleaning, and reassembly. This kit allows you to address common problems such as worn fuel lines, inadequate fuel filtration, and faulty gaskets in one go, ensuring a more reliable and longer-lasting carburetor system after repair. It is an indispensable, practical, and economical wear part kit for motorcycle maintenance and repair. Main components and functions: Transparent fuel line: Material and properties: This fuel line is made of high-quality, oil-resistant PVC or transparent rubber, offering good flexibility and excellent aging resistance. It will not harden, yellow, or crack, even after prolonged use. Main function: Replaces the worn original fuel line. The transparency allows for direct observation of the fuel flow and quick detection of interruptions, air bubbles, or contaminants in the line, thus facilitating troubleshooting. Integrated fuel filter: Design and operating principle: A small, transparent plastic housing contains a high-performance filter element (e.g., made of paper, fibers, or sintered material). **Main function:** Installed in series in the fuel line, it effectively filters out fine contaminants such as dust, rust, and deposits, preventing them from entering the carburetor and contaminating sensitive components like the metering nozzle and needle valve. This prevents malfunctions caused by contaminated fuel. **Bakelite gasket (insulating and heat-damping gasket):** Material properties: This gasket, made of laminated phenolic resin (known as Bakelite), offers excellent electrical insulation as well as high mechanical, thermal, and oil resistance. **Main function:** Installed between the carburetor and the engine's intake manifold, it provides heat insulation and prevents direct heat transfer from the engine to the carburetor. This prevents "vapor lock" caused by overheated fuel in the carburetor chamber. It also insulates against sparking, thus increasing safety. **Paper Gasket:** Material Properties: This gasket consists of special gasket paper or composite materials that are oil, temperature, and age resistant and exhibit a certain degree of compressibility. **Main Function:** It ensures a flush seal between the carburetor and the intake manifold (or mounting plate). It guarantees a tight connection and maintains the intake vacuum essential for the correct operation of the carburetor.
