Do not shorten the piston skirts in any way: this would cause the crankshaft to
be unbalanced and therefore, would cause important vibrations, and a high
wear of the piston due to improper guiding.
Do not touch the oval section of the exhaust outlet. Modifying it in a
circular section, to connect it to an exhaust flange, for example, would result
in a significant decrease in performance.
If necessary, install one or more large volume radiators. The ideal operating
temperature must be between 45 and 55 °C
