Novarossi have released this set of 3 safe storage plugs, designed to cover all the openings on the engine. Most racers have multiple engines and this means that 1 or more engines are being stored away somewhere amongst your racing gear. A plastic bag gives some protection but it is not dust & oil proof, and that is where these plastic plugs come in. Placing them over the carburettor, fuel nipple and exhaust port, this closes the engine fully and keeps dust and debris outside the engine, and oil inside the engine. Available for both 3.5cc/4.66cc engines and 2.10cc/2.5cc engines.
