it after passing the lead through
the clamp.
D To the EXUP servo motor
E Pass the coolant reservoir tank
drain hose and fuel tank drain
hose through the clamp from the
outer side of the water pump inlet
pipe after routing it behind the
water pump breather hose.
The lengths of two hose ends are
allowed to be random. Any direc-
tion of cut edges can be ac-
cepted. (Only for the fuel tank
drain hose)
F Clamp the fuel tank drain hose
and fuel tank breather hose.A Clamp the leads so that they are
positioned inner of the vehicle
than the washer position after
routing them between the frame
and radiator stay. Align the clamp
position with the taping sections
of leads. Point the tip of the clamp
(surplus section) to the down
front side of the vehicle.
What the clamp fastens at this
stage are the handlebar switch
and main switch leads.

M There should be no exposure of
bared conductors due to the dis-
placement of the tube.
N Route the coolant reservoir tank
drain hose so that it is routed at
the innermost position to each
hose and lead.
O Can be routed in any order.
P Align the molded part of the fuel
tank drain hose with the stay 1.
Q Routing of the fuel tank drain
hose.
