Naraku racing 4-valve cylinder head for Yamaha Cyngus/ BWS 125cc 4-stroke air-cooled scooters with big bore cylinder kits.
The valves and springs have been stiffened to allow the engine to be pushed further than ever. The number of valves has of course been doubled allowing more power to be extracted from the engine. The inlet and exhaust outlet has been opened to 25 and 24mm respectively.
Not suitable for 125cc cylinders. This head may be adaptable to YBR125 with big bore cylinders.
