How much oil do you put into a 2005 yz 125? - 2004 Yamaha YZ 125

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

The clutch and gearbox share the same oil. The oil for the motor is 10w40. Stick with the major brands; Pennzoil, Quaker State, Mobil, Yamalube or Shell.

I have a dennis kirk book, the correct spark plug is a --BR9ES--(NGK)

i always used SAE 10w-30 oil on all my dirtbikes,
no transmission fluid

for the chain you should move the back tire back until the chain is at a snug tension
