S&S Engines
Complete S&S engines
Do you have a custom project in the basement or garage and are still missing the engine? Then you've come to the right place: we offer Knucklehead, Panhead, Shovel, Evo, with different displacements and completely assembled by S&S from new parts.
Another scenario. The recently acquired project gives problems. You opened up the engine and experience: the connecting rods wobble, all bearings have considerable play, the pistons are from Moskwitsch stocks and have different diameters, valves from who-knows-where leak and prevent proper compression. In short, everything is worn out. In this situation the complete engine from S&S is just what the doctor ordered!
The mounting points are the same as on original cases. If you choose a version with longer cylinders, you have to make sure that the rocker covers do not interfere with the 4-speed frame. Minor milling work must be taken into account at this point. Unspectacular, but it should be mentioned here.
Proven Performance
When asked about a manufacturer of high-performance engines, the majority of enthusiasts of American V-Twin engines mention the name S&S. The engines still power more custom bikes than all other brands put together and they have always been our first choice when it comes to upgrading standard bikes with extra power and performance. The sometimes rather tame standard Harleys are transformed into respectable muscle bikes in no time. S&S sums this up very aptly in their motto "Proven Performance".
Compared to today, the typical stroker engines of the 60s and 70s were rather crude units and earned a reputation for unreliability and short service. But that was a long time ago and S&S has made great progress in its company history, not only in terms of performance, but also in terms of reliability and mileage.
Twice the performance with the same service life as an original engine - is that possible?
Unfortunately, performance depends on some restrictions, which - depending on your country - have to be observed, on order to not attract too much attention from the "authorities". Longevity is also possible, the materials used make this possible. If you obey the rules when running in and prepare the engine for its years of service with good sense and only turin it on after the S&S engine has warmed up properly, you will ber ylikely experience a long service life. Answer to the question in one sentence: In our opinion, buying a factory-assembled S&S engine is the safest way to achieve this goal.
How do you know you have a genuine S&S engine?
All complete engines from S&S come with a certificate that confirms that it is "The Real Thing". If this certificate is missing, you should assume that the unit was not assembled by S&S in Viola WI, USA. The certificate belongs to the engine like the registration certificate belongs to the motorcycle. When reselling the Harley, the trustworthy seller will provide the certificate.
Are there performance data sheets for S&S engines?
The power output of the individual engine depends on parts such as the air filter and exhaust. A data sheet can only be created for a specific configuration. If you need performance data for registration, you therefore have to go to a test bench. If you need the engine capacity for tax purposes, check the certificate.
