Description

Description for S&S Cycle 551 Gear Drive Easy Start Cams Complete Kit

• Start any engine regardless of displacement or compression ratio with a stock starter

• The new Easy Start Cams from S&S Cycle make hard starting obsolete

• Heres how it works: Each of the two exhaust cam lobes are equipped with a spring loaded compression release lobe on the “heal” of the cam at the point where the valve would normally be fully closed, the lobe holds the exhaust valve open slightly at cranking speed, this releases some of the compression, making the engine much easier to crank , 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

• Allows a stock starter and battery to start nearly any engine

• Don't get caught “dead” without them!

Big Power. Straightforward install. Noticeable idle. I used these cams in conjunction with as S&S 96" kit and a Dynojet kit. The results were more than I expected. Pulls hard on my 2006 Ultra Classic. The goal was to gain enough torque to prevent the need for downshifting when climbing grades in 6th gear with a headwind. The upgrades returned much more than the expectation. Overpowers the clutch in 6th gear on occasion. Buy the pushrod kit as instructed.
