The engine oil should be replaced after the first 1,000 km,
and then every 6,000 km for the 125cc version and 12,000
km for the 250cc version. The engine must be drained
through the net filter draining cap «B" on flywheel side; in
addition, to facilitate the drainage, oil dipstick «A" should be
loosen. Once the engine oil has been drained, remove oil
Since a certain oil quantity remains inside the circuit, the fill-
up must be carried out with 600-650cc of fresh oil poured
through filler cap «A". Hence start the vehicle, let the engi-
ne run for a few minutes, and then shut it back down; after
approx. five minutes, check the level and top-up if neces-
sary, without exceeding the MAX mark.
RENEW THE OIL WHEN THE ENGINE IS HOT.
Synthetic oil SAE 5W/40 of higher quality than API SJ
Locking torques (N*m)
Engine oil drain plug 24 - 30 N.m
In four-stroke engines oil is used to lubricate the valve gear
components, the crankshaft bearings and the power plant. A
lack of engine oil can cause serious damage to the engine.
In all four-stroke engines, oil deterioration and consumption
are, to some extent, normal, especially during running-in.
Consumption partly depends on the riding style (for example,
constantly riding at full throttle increases oil consumption).
