The camshaft is 1 of the key comp1nts of the engine. The hardness of the cam tip and the depth of the white layer are key technical indicators that determine the service life of the camshaft and the efficiency of the engine. The large angle camshaft can extend the valve opening time, increase the valve lift, and make the intake and exhaust valves open early and late, allowing more air to enter the cylinder to improve the engine's medium and high speed power and output. It can enhance 20% output power.This item is in the category "eBay Motors\Parts & Accessories\Motorcycle & Scooter Parts & Accessories\Engines & Engine Parts\Engine Rebuild Kits & Components".
