How much oil do i put in my 2003 Yamaha yz125 dirt bike

SOURCE: oil level YZ 125

Hello....for the crank case you will want to use Yamalube 4 (10w-30) or an equivalent SAE 10W-30 SE motor oil. There is not a dip stick on the bike, Need to measure teh oil in accordance with Yamaha specs. You will need to check the owners manual or contact the local dealer service department and should be able to tell you how much needs to be added. If you don't have good 1qt mix cup you can get one at a good motorcycle shop. These are very help full in accurately measuring your premix oil for the fuel as well. Hope this helps

Synthetic motorcycle oil is a must. The book probably recommends 5w30. There is a ton of videos on youtube for your bike, including the oil change, some great tips. Check them out. It would take me hours to explain it. Hope this helps.
