Beschreibung

Converting from the stock chain driven cams to gear driven cams improves valve timing accuracy by eliminating timing chain lash. Another advantage is that you loose the chain tensioner shoes that wear out or even fail. Bolt-in cams do not require head work.
Easy Start cams start any engine regardless of displacement or compression ratio, using your stock starter. Consequently, they save your starter and battery. They work automatic, no buttons to push. The two exhaust cam lobes are equipped with a spring loaded compression release lobe on the "heel" of the cam at the point where the valve would normally be fully closed. The lobe holds the exhaust valve open slightly at cranking speed. This releases some of the compression, making the engine much easier to crank. Once the engine starts, and rpm increases, the compression release lobe is centrifugally retracted and the engine runs normally, with full compression, and without any loss in performance. Easy Start cams have been tested for 100,000 accumulative starts and over 150,000 road miles without breakage or compression release failure.
Complete S&S gear drive camshaft kits contain front and rear cam, all gears, gear cover gasket, bearings, retaining ring, o-ring, thread lock and instructions. For those who have already converted gear drive and just want to change to Easy Start cams and/or valve timing we also have cams with just the inner gears available.

Notes: Stock valve springs in 1999 thru 2004 Twin Cams can handle cams with valve lifts as high as .515". Stock valve springs in 2005 thru 2017 Twin Cams can accommodate valve lifts up to .590". The OES and 557 grind cams can be installed using the stock pushrods. However, we recommend S&S Quickee Adjustable pushrods ZPN 752108 for easy installation of all S&S cams.

OES grind: Original Equipment Specification (OES) A bolt-in replacement cam with stock cam timing is designed for riders with stock engines. Does not require tuning. Bolt-in stock. Equivalent to OEM A-Grind

509 grind: Designed as a bolt-in, high torque cam for 1999-'06 models. 180 psi cranking compression, no need for compression releases. For 88 CID engines with stock compression ratio. Idle-4500 rpm. Bolt-in torque.

510 grind: Designed as a bolt-in cam for 88, 95, and 96 CID engines with compression ratios below 9.7:1, stock, un-ported heads and stock valve springs
