Section 08 COOLING SYSTEM
Subsection 01 (COMPONENTS AND CIRCUIT)
LOW SPEED OPERATION
1. Water entering regulator valve
2. Water exiting regulator valve (less restriction)
3. Water injected in the muffler
At higher speed, water pressure increases in the
supply hose of the regulator valve and gradually
overcomes the return spring of the regulator valve.
Less water is being delivered to the injection fit-
ting at the tuned pipe.
HIGH SPEED OPERATION
1. Water entering regulator valve
2. Water exiting regulator valve (more restriction)
3. Water injected in the muffler

Adjustment
The water flow regulator valve has been calibrated
at the factory and should not be modified.
NOTE: Water flow regulator valves ordered from
the parts channel are also calibrated.
If the maximum engine speed cannot be attained
or if the engine has poor performance, the water
flow regulator valve should be considered in the
troubleshooting of the problem.
Disassembly
Remove the cover no. 4 of the valve by releasing
the spring no. 3.
Firmly hold cover to valve base. The spring
inside the valve is applying a pressure against
the cover.
