How to change the gearbox oil on a 2-stroke motorcycle

We start by positioning an environmental mat to protect the floor (and the planet! 😉). Put your bike on the mat and a drain pan under the engine.

Remove the filler cap and unscrew the drain plug under the motor with a combination wrench.

Let the oil drain into the pan.

When the drizzle of oil becomes thinner and the oil change is almost complete, tilt the bike from side to side to get every drop of oil out.

Once the oil has been properly drained, clean the drain plug and the gasket span with brake cleaner and a cloth.

Replace the sealing washer and tighten the drain plug to the torque recommended in the manufacturer's manual.

You can now fill the crankcase with new oil. To find out how much oil you need, please refer to your manufacturer’s manual. Sometimes it is also engraved on the clutch housing.

If your bike has a check bolt, unscrew it to check the oil level.

When the maximum level is reached, the oil starts to flow slightly. You can then tighten the check bolt and clean.

Close the filler cap and we’re done!
