Throttle Position Sensor (Tps) Setting - Suzuki VZ800 Service Manual

• After making sure that the steel ball stays steady at the center
line, disconnect the hose from the No. 1 throttle body vacuum
nipple and connect the next hose to this vacuum nipple.
• Turn air screw to bring the other steel ball 6 to the center
line.
The balancer gauge is now ready for use in balancing the throt-
tle valves.
Throttle valve synchronization
Using the vacuum balancer gauge, inspect the throttle valve
synchronization in the same manner of the digital vacuum tester.
Pay attention to the following points:
The vacuum gauge is positioned vertical level, and in this posi-
tion the two balls should be within one ball dia. If the difference
is larger than one ball, turn the balance adjusting screw on the
throttle body and bring the ball to the same level.
A correctly adjusted throttle valve synchronization has the balls
in the No. 1 and No. 2 at the same level.
