S&S CYCLE MR103 Easy Start Camshaft kit — Gear type – 06-16 Dyna, 07-16 Touring, 07-15 CVO, 10-16 Trike, 07-16 Softail

The MR103 Easy Start Camshaft kit makes starting easier by temporarily reducing crank compression during initial rotation. Once the engine fires and rpm increases, the compression-release lobe retracts centrifugally so the engine returns to full compression and runs normally without any loss in performance. 🇺🇸🔧

• Designed as bolt-in cams for 103" engines with stock compression from 9.7:1 up to 10.5:1.
• Provides more power across the rpm range, with best results between 2500 rpm and 5500 rpm.
• Works well with stock un-ported heads and is also suited to S&S CNC ported heads.
• Includes camshafts, gearcover gasket, bearings, retaining ring, o-ring, thread lock and instructions.
• Installer must check coil bind, valve-to-valve clearance and valve-to-piston clearance. Not for models with OEM compression releases.

Made in the USA. Follow the included instructions for proper installation and clearance checks to ensure safe, reliable operation.
