 SynchroKing 2 and 4:

Q: What is the measuring range of the SynchroKings?

A: The range is 500 mmHg / 0.66bar  /9.66 psi.


Q: Is the SynchroKing suitable for my specific motorcycle?

A: Our SynchroKing devices are compatible with any type of piston engine in both cars and motorcycles, as long as they have M5 or M6 test ports in the inlet manifolds.


Q: Can the SynchroKing be used to adjust the air and fuel?

A: No. Our SynchroKing devices are used to balance the pressure in the inlet manifolds only. However, if you are looking to measure and adjust your air/fuel ratio, our LambdaKing can help.


Q: My bike has a vacuum post built into the inlet manifold, which is not removable. Can I still use the SynchroKing?

A: Yes, if the post is around 5-7mm in diameter, the hose would slip over the post. Alternatively you can replace the post with the M5 or M6 nipples that are supplied with each SynchroKing device.


Q: Can I use the SynchroKing 4 on a twin?

A: Yes, you can. The SynchroKing 4 will automatically ignore any of the four channels that are not in use, so it is suitable for 2,3 and 4 cylinder vehicles.


LambdaKing 1:

Q: Can I measure the air-to-fuel ratio by inserting the sensor into the exhaust?

A: No, the sensor requires reference air from the atmosphere to function, so inserting it into exhaust will not work.


Q: Does the LambdaKing1 work with fuels other than gasoline such as Diesel or LPG?

A: No, the current version of the LamdbaKing1 is not compatible with fuels other than  gasoline. We are planning to include this functionality on future versions.


Q: Can I use the LambdaKing 1 whilst driving the vehicle?

A: The device is not designed for on-road use, but it should work alright.
