Compression tester for mopeds, mopeds, motorcycles and cars.
The compression tester has an M14x1.25 connection (standard moped spark plug thread) and an M12x1.25 connection.
The compression tester can be used to assess whether the compression pressure in the cylinder is still sufficient or whether the piston rings or the piston should be replaced. As a rule of thumb, a pressure of 6 to 7 bar and higher can be regarded as OK for 50 to 75 cc engines when cold.
Technical data of the pressure gauge:
- Measurement range: 0 - 21 bar
- Tolerance: +/- 3 %
- Connection hose: 300 mm
- Connection: MF 14 x 1.25 / MF 12 x 1.25
Instructions for use:
- Disable the ignition before starting
- Set the throttle to full throttle during the testing process
- Rotate the engine at starting speed for 3 - 4 seconds
- Take the measurement with the engine cold and warm
