How it works
This version includes our new head (that can be disassembled) that ensures significantly lower operating temperatures in the cylinderpiston unit for improved reliability and performance.
In this new head, a larger portion of the combustion chamber comes into contact with the coolant to keep temperatures within an ideal range for enhanced engine efficiency.
The compression ratio has also been modified to accommodate the new temperature values.
