S&S Cycle MR103 Easy Start Gear Drive Camshaft Kit with Inner Gears Only - 330-0467

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
Allow 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
Available in chain drive and gear drive versions
All chain-drive cams include installation kit
All gear-drive cams include 4-gear set and installation kit
Gear-drive cams also available with inner gears only; intended for cam replacement for motors that have already been converted to an S&S gear-drive system
Made in the U.S.A.
