  • Page 44: Engine Oil Level

    Engine oil level In 4-stroke engines, engine oil is used to lubricate the distribution elements, the bush- es and the thermal group. An insufficient quantity of oil can cause serious damage to the engine.In all four-stroke engines, a loss of efficiency in oil performance and consumption should be considered normal.

  • Page 45: Engine Oil Top-Up

    Engine oil top-up Always check oil level before topping-up and add oil without exceeding the MAX level. Getting an oil level between the MIN and MAX levels requires ~ 400 cm³ of oil.
