551 Easy Start Camshaft Kit

  • Allows for easy start by initially reducing crank 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
  • Optimized for 88"/96"/103" to 106" Touring bike with slip-on mufflers and 9.0:1 to 9.0:9 compression with stock starter
  • Bolt-in for stock or mildly modified Touring models
  • Greatly improves low-end and midrange torque
  • Strongest from idle to 4000 rpm
  • Includes camshafts, gearcover gasket, bearings, retaining ring, o-ring, threat lock and instructions
  • Made in the USA
  • Not recommended for compression ratios of 10.0:1 or greater.
  • Installer must check coil bind, valve-to-valve clearance and valve-to-piston clearance.
  • Not for models with OEM compression releases.
  • Can be used with stock pushrods, lifters, and springs (unless noted).
