S&S, Easy Start gear drive 640 camshaft kit (IOG) - 99-06 Twin Cam (excl. 2006 Dyna) (NU) 974651 mount kit for tapered fork. 640" valve lift. IOG = gear drive cams with Inner & Outer drive Gears. Complete kit with installation hardware, bearings and gasket. For 95" up with 10. 5: 1 to 11. 5: 1 CR (stock in S&S 124" engines). Easy Start Cams make starting easier by reducing the build up of cranking pressure in the cylinders during starting. This is done by lifting the exhaust valve slightly of its seat, with a spring loaded compression release lobe inside the camshaft.
