4- Fuel System

Fuel hose must be clamped securely with proper clamps and can not contact any hot surfaces where it could melt or catch fire, causing
serious injury or death.

The X-Wedge engine requires a fuel supply of 58 psi to the fuel injectors. A fuel pump and regulator assembly is available from S&S® (PN 55-5089)
that is designed for being mounted inside the fuel tank. Other pumps may be used as long as the supply is regulated to 58 psi and it provides a
minimum supply of 45 L/hr. It is recommended a fuel filter that filters to 10 um be used.

Connections
Fuel is supplied to both fuel injectors from a tee located in the fuel hose between the injectors. The engine is delivered with an extra length of fuel
hose connected to the tee for connection to the fuel pump. This hose may be trimmed to fit your application if needed. Position fuel hose to avoid
contact with hot cylinders or other engine parts.

5- Throttle/Cables
Throttle Requirements

NOTE: S&S throttle bodies require the use of a two cable, pull open - pull closed throttle assembly. All models equipped with a single cable throttle
mechanism must be converted to the two cable, pull open - pull closed type. S&S offers a variety of these throttle assemblies.

Single, braided wire cable throttle mechanisms cannot mechanically close the throttle. If the throttle inadvertently sticks in the open
position, loss of control of motorcycle and personal injury to you or others may result.

Any motorcycle equipped with single cable throttle system must be converted to a two cable system. Kits with 36" (91cm), 39" (99cm), 42" (107cm),
48" (122cm), or 52" (132cm) length cables are available. Throttle assembly kits may be ordered separately. See descriptions on next page.
Two cable throttle systems designed for a butterfly type carburetor/throttle body have cable fittings that can simply be “plugged in” to the S&S
throttle body throttle linkage.

Optional S&S Two Cable Throttle Kits
Kits fit 1” (25.4mm) O.D. handlebars and can be used on most chassis. An adapter sleeve is available for use with handlebars having 7/8” (22.2mm)
diameter ends. Fittings on provided cables readily “plug in” to S&S® throttle bodies. Kits include one opening side cable, one closing side cable, left
and right handlebar grips, and handlebar clamps.

Gasoline is extremely flammable and explosive under certain conditions. Do not smoke or expose gasoline to sparks or open flame.

Gasoline fumes are toxic when inhaled. Perform installation in a well ventilated area away from open flames or sparks. Unwarranted
sparks and inadvertent engagement of starter while working on electrical components can cause serious injury or death.
