Labels
Two unique labels with the headings “Vehicle Emissions Control Information” (VECI) and “Vehicle Evaporative Hose Routing” are provided with the
engine. The VECI label contains the engine family identification, engine tune-up specifications, and the serial number of your engine. The Vehicle
Evaporative Hose Routing label shows the proper evaporative system hose routing for the engine.
Both labels must be installed on the motorcycle frame or on a part that is permanently attached to the frame and must be located so they are visible
with the seat removed.
NOTE: Clean the areas where the labels will be affixed before installing them. Once affixed, the labels are permanent and can not be removed without the
label being destroyed.
Evaporative System
To meet evaporative emission regulations the evaporative system must be installed on the motorcycle. The evaporative canister, vapor valve, and
R11-A hose is included with the engine for hooking up the evaporative system. It is required these components are installed and the following
requirements for the fuel tank and cap are met.
The fuel tank must be constructed out of metal and shall have a maximum capacity of 5 US gallons or less. The fuel tank shall be located such that
no surface of the tank is closer than 1/8 inch to the engine. A fuel tank vent must be provided to vent fuel vapors out through the vapor valve to the
evaporative canister, and a Harley-Davidson® #61272-92B or equivalent fuel cap must be used.
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 California X-Wedge™ Engines are different from those
for other S&S Engines.
• The camshafts supplied in S&S California 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 and California State Law.
• Throttle bodies with S&S California 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 California X-Wedge Engines contain a locked file and are not adjustable. The tuning instructions included
with the Pro Tune 2 CD do not apply.
