S&S Cycle Electric Compression Release Kit 90-4915
|
|
Our Price: $272.95
|
|
|
Designed to be used in S&S cylinder heads for Twin Cam, 4in. bore Evolution big twin, and Super Sidewinder Plus style S&S engines
Consists of a small valve that opens during starting and allows a portion of the cylinder pressure to escape into the exhaust port of the cylinder head
Reduced cylinder pressure makes it easier for the starter to turn the engine
When the engine starts, the valve closes and the engine runs normally, with full compression
Electric compression releases are solenoid operated
They automatically open when the starter button is depressed and automatically close when the starter button is released
When installed on SSW+ or twin cam style S&S engines, S&S electric compression releases require the use of S&S die-cast twin cam style rocker covers or similar covers with a central hole or chimney
The chimneys in the rocker covers are required to provide clearance for the solenoids that operate the compression releases
Electric compression releases are compatible with stock or S&S rocker boxes for Evolution engines

Our Price: $317.95
|
|
|
Designed to be used in S&S cylinder heads for Twin Cam, 4in. bore Evolution big twin, and Super Sidewinder Plus style S&S engines
Consists of a small valve that opens during starting and allows a portion of the cylinder pressure to escape into the exhaust port of the cylinder head
Reduced cylinder pressure makes it easier for the starter to turn the engine
When the engine starts, the valve closes and the engine runs normally, with full compression
Manual compression releases are activated by a cable similar to a choke control
Before starting, the handle is pulled, which opens the compression releases. When the engine fires, the increased cylinder pressure automatically closes the compression releases
Can be used with any style rocker cover
