S&S Cycle 570 EZ Easy Start Camshaft Kit For Harley Twin Cam
If you’ve put together a hot bike – or if reliability is paramount – an S&S Easy Start Cam Kit should be on your list. Don’t bother fooling with compression releases or massive-output batteries and super-high-buck starters. S&S designed the Easy Start cams with performance in mind, but then revamped the design to give you great power on a cam that starts easier than a dirtbike. At the center of the cam lives a centrifugally retracted, spring loaded compression release lobe milled into the heel of each exhaust lobe. At cranking speeds, the lobe bumps the exhaust valve open slightly during the compression stroke, making the engine much easier to turn over. Once the engine fires and reaches 800 RPM, the lobe swings out of the tappet roller path, allowing the engine to run normally and with full compression. Ain’t technology great
Features:

Start any engine regardless of displacement or compression ratio with a stock starter

Save your starter and battery; tested for 10,000 starts without running battery down

Allows for easy start by initially reducing cranking compression, but 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
