S&S CYCLE MR103 Easy Start Camshaft kit — gear drive – 06, 08-10, 12-16 Dyna, 07-15 CVO, 10-11, 13 Touring, 10-16 Trike, 07-16 Softail

The MR103 Easy Start camshaft kit allows easy starting by initially reducing crank compression; once the engine starts and rpm increase, the compression release lobe is centrifugally retracted so the engine runs with full compression and without loss of performance.

Designed as bolt-in cams for 103" engines with stock 9.7:1 compression up to 10.5:1, the kit produces more power across the rpm range with best results between 2,500 and 5,500 rpm.

• Includes camshafts, gearcover gasket, bearings, retaining ring, o-ring, threat lock and instructions.
• Includes a four-gear set; due to the inherent characteristics of gear drives, there may be increased valve train noise.
• Works with stock, un-ported heads and is also suitable for S&S CNC ported heads.

Installer must check coil bind, valve-to-valve clearance and valve-to-piston clearance before final assembly. Not for models with OEM compression releases.
