- Fuel Tank, Air Cleaner Housing (see Fuel System chapter}
- Vacuum Switch Valve
Connect a vacuum gauge [A] and syringe [B] or fork oil level gauge to the vacuum hoses as shown.
Special Tool - Fork Oil Level Gauge: 57001-1290
Air Flow [C].

Gradually raise the vacuum (lower the pressure) applied to the vacuum switch valve, and check the valve operation. When the vacuum is low, the vacuum switch valve should permit air to flow. When the vacuum raises to valve closing pressure, it should stop air flow.

★ If the vacuum switch valve does not operate as described, replace it with a new one.
Note. To check air flow through the vacuum switch valve, just blow through the air cleaner hose.
Vacuum Switch Valve Closing Pressure (Open — Close)
Standard: 57-65 kPa (430-490 mmHg)
- High Vacuum [A]
- Secondary air cannot flow [B]
