• Fuel pressure
• Minimum: Airbox pressure + 2.18 psi (0.15 bar)
• Normal : Airbox pressure + 3.63 psi (0.25 bar)
• Maximum: Airbox pressure + 5.08 psi (0.35 bar)

WARNING
Exceeding maximum allowed fuel pressure will override the float
valves of the carburetors and lead to engine failure.
NOTE
On the S201, fuel pressure is directly measured as difference between
fuel and airbox pressure. Therefore, the operating range as indicated
on the EMS is 2.18 to 5.08 psi.
