Weld the bush on the exhaust pipe
12-15 cm from the piston.
The bush is mounted on the exhaust pipe.
The distance should be 12-15 cm from the
backside of the piston. Do not drill a hole
in the exhaust pipe before you have
welded the bush on the pipe.
After the bush is welded on the exhaust
pipe, drill a 4.1 mm hole in the middle of
the bush through the exhaust pipe. Be
careful not to damage the pipe on the
other side when you drill through the
pipe.
Mount the sensor in the bush.
After the hole is drilled, the sensor is
pushed all the way in and tightened. Fix
the cable to the seat, and all the way to
the Main Box, so it is well protected.
The cable is mounted in the connector
named TEMP 3 on the Main Box. Tighten
the connector hard with your fingers.
Water sensor
This is the sensor for measuring the water heat. Use either TEMP 1 or TEMP 2 for the water
sensor. When you drive a kart with water cooled engine, the heat of the cooling water is of course
important for the performance of the engine.
