Section 04 ENGINE (2-STROKE)
Subsection 01 (LEAK TEST)
NOTE: Engines with the RAVE system, the boot
(carburetor-equipped engines) and O-ring can be
checked for leakage with the valve in place. Sim-
ply remove the cover to expose the parts.
Make sure the spark plugs (and the air/fuel rail on
DI engine) are installed and tightened.
Block pulse hose (carburetor-equipped engines)
using a hose pincher.
NOTE: Do not block the rotary valve shaft hoses
(if so equipped).
Install pump to the exhaust plate fitting.

Activate pump and pressurize engine to 34 kPa
(5 PSI).
CAUTION: Do not exceed this pressure.
Wait 3 minutes and check if pressure drops; if so,
verify all testing components.
If kit components are not leaking, verify engine
jointed surfaces as per following areas:
– spark plugs
– direct injector sealing (DI engines)
– cylinder head gasket
– cylinder base gasket
– crankcase halves
– rotary valve cover (except DI engines)
– engine plugs
– exhaust manifold
– intake manifold (717 engines)
– intake flanges (DI engines)
– oil injection pump (717 engines).
Check also small oil injection pump lines and fit-
tings; check for air bubbles or oil column going
toward pump, which indicate a defective check
valve.
