RAVE VALVE GENERAL INFORMATION

The exhaust valve is solenoid-actuated via a Bowden cable.
The ECU determines engine rpm based on primary circuit
frequency input and operates the solenoid within a preset
rpm range.
NOTE Using the exhaust valve on type-approved 11kW
vehicles makes such vehicles illegal to ride on public roads.
Any such vehicles equipped with this valve may only be used
for racing or on closed-circuit tracks.
"RAVE" valve operation
• The exhaust valve opens between 500 and 2500 rpm
to allow for valve stem self-cleaning.

•
Beyond the actuation point, the valve stays open.
