SOURCE: Engine oil
They take just under 1ltr of oil. you can check the level is correct by running the engine till its warm and pulling out the dipstick located near the head stock on the frame. If the level is low then add more oil, be careful not to overfill as the later model WR's expel excess oil into the air box, this can make a mess of your air filter.

Check your jets in your carbs and also could be bad fuel. Poor some sea foam in it and some new fuel and check to see if the inline filter is plugged and check your air filter as well.

Yamaha doesn't give an amount for some of its bikes, just a measurement from the top of the tube down to the oil.

you will need about 1.2 litres of four stroke motorcycle engine oil 20w40 and an oil filter, and change it every few rides. Very important for long engine life.
You use the dip to make sure it has enough oil, but you have to start the bike and run it for a couple of minutes then dip the oil with the stick. Do not use car oils as the clutch may slip.
