ANDREWS Valve Kit (Manufacturer Ref: 288121)

This ANDREWS camshaft kit, machined from alloy steel billets and heat-treated in the United States, is aimed at riders seeking a more responsive engine on their Touring and Vintage/Classic twin-cylinder bikes. Designed for chain drive, the shaft is bolted to enhance torque with the original compression and fits both carbureted and fuel-injected engines. Supplied with the front support bearing, it accepts original springs and pushrods.
