Fuel Pressure Inspection
This inspection can determine which trouble the DFI
system has, mechanical or electrical trouble.
It is preferable to measure the fuel pressure while run-
ning the motorcycle when the trouble has occurred in
order to know symptom well.
Be sure the battery is fully charged.
Remove the fuel tank (see Fuel Tank Removal).
Be sure to place a piece of cloth around the fuel hose joint
and the delivery pipe.
Insert a minus screw driver [A] into the slit on the joint lock
Turn the driver to disconnect the joint lock.
Pull [C] the fuel hose joint [D] out of the delivery pipe.
Be prepared for fuel spillage; any spilled fuel must
be completely wiped up immediately.
When the fuel hose is disconnected, fuel spills out
from the hose and the pipe. Cover the hose connec-
tion with a clean shop towel to prevent fuel spillage.
Install the fuel pressure gauge adapter [A] between the
fuel tank outlet pipe [B] and the inlet pipe [C] to the deliv-
ery joint [D].
Put the fuel pressure gauge adapter outside the frame.
Connect the pressure gauge [E] to the fuel pressure
