ceed with an engine leak test. Refer to LEAK
TEST.
COMPONENT REMOVAL WITH
THEENGINEINSTALLED
Most engine components can be removed with
engine on vehicle such as:
– cylinder head
– cylinder(s)
– piston(s)
– RAVE valve(s)
– reed valve(s).
CLEANING
Discard all gaskets and O-rings. Use Loctite Chis-
el (P/N 413 708 500) to clean mating surfaces.
Clean all metal components in a non-ferrous metal
cleaner.
Scrape off carbon formation from cylinder exhaust
port cylinder head and piston dome.
NOTE: The letters “AUS” (over an arrow on the
piston dome) must be visible after cleaning.
Clean the piston ring groove with a groove cleaner
tool or with a piece of broken ring.
RAVE VALVE BASIC OPERATION
NOTE: RAVE stands for Rotax Adjustable Variable
Exhaust.
The RAVE valves change the height of the exhaust
port to enhance the engine powerband and torque
according to the engine RPM and throttle position
(e-RAVE on Power Tek and SDI engines).
All Engines except Power Tek and SDI
Exhaust pressure is used to inflate the bellows
and open the RAVE valves at the proper engine
RPM.
Power Tek and SDI Engines with E-RAVE
AccordingtoengineRPMandthrottleposi-
tion, the ECM activates a solenoid which allows
crankcase positive pressure to inflate the bellows
and open the RAVE valves.
