FUEL DELIVERY PIPE ASSEMBLY REPLACEMENT PROCEDURE
When working with the fuel system, work in a well ventilated area away from any flame
or ignition sources. Store the motorcycle in an area away from any flame or ignition sources.
NOTE: The fuel delivery pipe assembly can be removed from the throttle body without
removing the throttle body assembly from the motorcycle.
1) Refer to section 6 of the service manual to remove the fuel tank and the air cleaner box.
Place shop rags over the bore of each throttle body to prevent anything from falling into
the engine through the throttle bodies.
2) Remove the wire harness clamp, disconnect
the fuel injector couplers A and move the
harness aside.
3) Remove the four fuel delivery pipe assembly
mounting screws and remove the fuel delivery
pipe assembly.
4) Replace the o-rings and seals with the new
parts supplied in the kit (apply a small amount
of engine oil to the o-rings and seals to ease
the installation of the injector).
To prevent damage to the o-rings or seals, don't turn the injector when pushing it into the fuel
delivery pipe and throttle body respectively.
Install the new fuel delivery pipe assembly in the reverse order of removal.
Fuel Delivery Pipe Mounting Screw Torque: 5 N.m (0.5 kgf.m, 3.5 lb-ft)

pipe.
DO NOT overtighten the harness clamp.
6) Connect the fuel tank, remove the shop rags from over the bore of each throttle body,
and run the engine, checking for fuel leaks.

has completely seated and locked (clicked) into position before turning on the ignition switch.
