Operators Manual
SETTING OF THE EXHAUST VALVE TIMING
Tools required:
• Allen key 4 mm or Socket wrench 8 mm
The opening time of the exhaust valve is set in the ECU and depends on the engine
speed. However, the ECU allows two different modes of the exhaust valve opening. These
can be selected by connecting an additional cable to the cylinder head cover.
ATTENTION
The ground wire must be continuously connected.
This is important for the general function of the engine.
Variant 1: Additional cable on battery ground
A:
See Ground wire
The additional cable is NOT attached to the ground wire. The control of the exhaust valve
timing is activated at 9100 rpm.
NOTE
Isolate the additional cable with an electrical/insulating tape to the ground wire so
that a possible contact with the engine ground does not affect the function.
B:
See Ground wire
The additional cable is attached to the ground wire. The control of the exhaust valve timing
is activated at 8800 rpm.
