Motorcycle Engine. Start It Up Every Time.

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 for 1999-up big twins. Available in chain drive and gear drive versions. Don’t get caught dead without them! Watch this 4-minute video.

    Pretty interesting- beats me forgetting to flip my compression releases all the time…..

    Is this not a take off in principal of the Porche/HD VROD motor design where, what is it, the exhaust cams do same in principal allowing the vrod the use of such a small/compact battery in its tight frame package with a bit of compression on their motor also? Wonder is this evolved from one of their,Porche, race car crankover principals initially.

    I wonder if they will reduce Torque a bit !

    There is very little new under the sun. Japanese bikes have used this technology for years and I say, good on S&S Cycle for adopting it. And, as J says, it means not having to reach down for the manual compression releases when stalled at the lights or wherever.

    After they disengage at about 700 rpm they don’t have any effect on the cam timing. No loss of TQ/power at low rpm. In fact, because of this we can now design cams that shorten the timing up to get the most low end power possible without worrying about hard starting. These are similar to other technologies that have mechanical compression releases on the exhaust cam. The difference is most of them (V-rod, Metric) are overhead cams, not pushrod motors with roller lifters. Getting it to work with roller lifters was the trick.

    Good response Scott, most are understanding of the ohc vs pushrod differences and the effort you undertook to apply similar as it is good to see S&S spend the time and money to develop it for their platform base as the concept has worked well and will surely save on starters/batteries, etc.

    Another question I was alluding to but could have been clearer on is; can S&S define the difference in cranking power range requirements with the new cams as to assist in defining battery requirements, i.e., that may add to the value of the design to afford cleaner/smaller packaged batteries/requirements that may lead to/on the custom bike frame design platform applications.

    Big motor compression release works fine… this another way to take $$$ out of our pockets.

    Grayhawk, We may be able to help you with power requirements, or at least the difference in amps. Every application will be different however so you may want to contact S&S directly and talk to us about your question. If needed you could ask for me.

    As far as pricing is concerned, these cams are not much more than our std cams. In fact the the difference is much less than std mechanical or electric compression release costs, especially when you consider that no machining or other parts are required.
