The S&Scompression release system consists of a small valve that opens during starting and allows a portionof the cylinder pressure to escape into the exhaust port. The reduced cylinder pressure makes iteasier for the starter to turn the engine. When the engine starts, the valve closes and the engineruns normally, with full compression.FITMENT• S&S cylinder heads with compression release machiningOPTIONS• Manual release:Activated by a cable similar to a choke control, this slick system can be used withany style rocker cover.• Electric release:Solenoid operated, this system automatically opens and closes when the starter button is pressed andreleased. Convenient and simple, this is the best setup for big displacement high compression bikes.Requires S&S die cast rocker covers, see page 3-61.S&S ® Compression Release KitsDescriptionPart No.Electric 90-4915Manual 90-4925MSRP$321.95$359.951984-1999 BIG TWINS90-491690-4915Electric Compression Release Kit50-870153-004555-1009Parts forVictory®, Off-road& MetricRacingProductsTools and AccessoriesDescriptionPart No.S&S Cable Knob:Special billet accessory knob for manual compression 50-8701release (see picture)S&S Two-Piece Socket Kit:Allows in-frame installation of S&S compression releases 53-0045and protects wiring from damage during installation.S&S Compression Release Hole Plug 90-4916MSRP$15.05$83.95$9.85Replacement PartsDescriptionPart No.Silicone Solenoid Caps 55-1009Wiring HarnessUSA 2,3TÜV 2,5,655-1010Electric Compression Release Assembly 90-4914MSRP$3.65$105.95$138.95Tools & ShopSuppliesDealer Services& Promo ItemsWarranty &Company PolicyNOTESS&S rocker covers must be used with electric compression releases due to clearance requirements for the solenoids.Rocker covers must be removed when installing S&S® compression releases. If lack of frame clearance prevents removal of rocker covers, engine must be removedfrom frame for compression release installation.In most cases, S&S compression releases can be installed while the engine is in the frame with the special S&S two-piece socket kit, part #53-0045 .If cylinder heads are machined for S&S compression releases, but compression releases are not used, special plug part #90-4916 (two required) must be installed toseal the machined hole.Stock cylinder heads cannot be machined for S&S compression releases because there is not enough material in critical areas.OEM Cross ReferenceAppendix & Index3-80Order toll free 866-244-2673
