Label
A unique label with the heading “Vehicle Emissions Control Information” is provided with the engine. This label contains the engine family
identification, engine tune-up specifications, and the serial number of your engine.
The label must be installed on the motorcycle frame or on a part that is permanently attached to the frame and must be located so that it is visible
with the seat removed.
NOTE: Clean the area where the label will be affixed before installing it. Once affixed the label is permanent and can not be removed without the label
being destroyed.
Permeation
The EPA permeation standard applies to fuel tanks and fuel hose. To meet the permeation standard the following conditions must be met for the
fuel tank and fuel hose.
The fuel tank consists of the tank itself, and any components mounted directly to it excluding fuel hoses. This includes the fuel cap if it is mounted
directly to the tank. To meet the permeation standard the fuel tank must be constructed of metal and all gaskets on the fuel tank must have a total
exposed surface area of less than 1,000 mm
2 .
The exposed surface area of the gaskets is considered to be the surface area of the gasket that is exposed to fuel or fuel vapor. To determine the
exposed surface area of a circular gasket the following equation would be used:
Exposed Surface Area= a x 3.14 x d
where: a = thickness of the gasket
d = ID of circular opening
To determine the exposed surface area on an o-ring seal the following equation would be used:
Exposed Surface Area= 0.25 x 3.14 x (X2 – Y2)
where: X = ID of circular opening
Y = OD of inset groove for o-ring
The fuel hose used on the engine must also meet permeation standards. The permeation standard applies to any hose that carries fuel or fuel vapor
that is not vented to atmosphere. This includes, but is not limited to, the fuel hose from the tank to the fuel rail and any fuel tank crossover hose.
The fuel hose included with S&S® engines meets the permeation standards based on the design of the hose. This fuel hose may be used and can be
shortened if needed. Any additional fuel hose used that is not vented to atmosphere must meet R11-A or R12 SAE J30 specifications. Additional fuel
hose is also available from S&S.
INSTALLATION NOTES
S&S® Engines may include instruction sheets for individual components. Most instructions apply to all S&S Engines. In the following instances,
however, components or procedures supplied with and described for S&S 49-State Certified X-Wedge™ Engines are different from those for
other S&S Engines.
• The camshafts supplied in S&S 49-State Certified X-Wedge™ Engines are of proprietary S&S design. There camshafts have been designed to allow the
engine to meet exhaust emission standards. Substitution of camshafts with different specifications is not permitted and would be in violation of the
Clean Air Act.
• Throttle bodies with S&S 49-State Certified X-Wedge Engines are not to be adjusted. For service requirements, contact S&S Cycle Technical Services,
608-627-1497.
• Engine control modules included with S&S 49-State Certified X-Wedge Engines contain a locked file and are not adjustable. The tuning instructions
included with the Pro Tune 2 CD do not apply.
INSTALLATION INSTRUCTIONS
This S&S 49-State Certified X-Wedge Engine has been manufactured, assembled, and calibrated by S&S Cycle, Inc. Before proceeding, verify that this
engine fulfills the requirements for your motorcycle. Installing an S&S engine into a motorcycle requires specialized knowledge, skills, and tools. For
this reason installation should be performed by a professional mechanic.
Improper installation of engine or related components could result in injury or death to the operator and/or passenger and damage to
the motorcycle.
1- Engine Installation
Due to differences in the engine mounting locations a frame designed for the X-Wedge engine must be used. The engine must be mounted using
the four mounting points on the lower cases and with a top support between the cylinder heads that is tied into the frame. The top support brace
must connect the 3/8”-16 tapped bolt holes located on top of each cylinder head above the intake port and 7/16” grade 8 bolts must be used in the
lower mounts.
