Who does not know them, the fantastically beautiful 4T engines from SAITO! For years known for highest quality and reliability. SAITO motors from the time of the (FA)ignition motors have become known. Always in 4-stroke design, in black housing with golden valve cover ( GK") or simply in silver-colored housing. Later followed modern large-volume (FG) petrol engines in different cylinder numbers. These new petrol engines quickly enjoyed great popularity, and from the outset they were regarded as powerful and reliable. Gasoline engines have a lower fuel consumption than ignition motors and the fuel is also much cheaper. The electronic ignition makes it possible to start the engines without an annealing device, which significantly improves the operating comfort compared to earlier engines. Commercially available standard gasoline is usually used in combination with high-quality 2T oil in a 15-20:1 ratio. A manual and in English language is enclosed with the engine.
