SOURCE: 2003 YZ 250 Oil Change

Use 10w40 in the gearbox. Get the oil from your Yamaha dealer along with any filter your bike may need. Some bikes use an oil change as the "filter". To drain oil, get the engine warmed up and turn it off. Put a pan under the gearbox and remove the oil drain plug. Replace the oil plug when the flow becomes a slow drip. Change oil in late spring, the middle of summer and in early fall. Remember to lube the chain and adjust it when needed. Lubricate the cables with liquid graphite. Lastly, install a stock spark plug. Now go for a ride.

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

SOURCE: what oil should i have in yz 125 2 stroke

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,

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

What type of oil should i use in my bike? i have a yz 125 and it ran off of 20 - 50 should i use the same or what?

Hi,
That 20w-50 is a premium lubricant already, upgrading to synthetic is much costly but much better.
It depends on how you frequently maintained your lubricant changes. If that grade of oil does not make any problem, better stay with it!
Hope that clears your mind!
Thanks for using Fixya!

1997 yamah yz 125 lots of white smoke comeing out of pipe

How much was it smoking previously? Too much smoke (oil) is a whole lot better than not enough smoke (oil). If you are mixing the oil and gas then cut back on the mixture. Obviously it is out of balance. Put 1/2 gallon of raw gas in the tank to cut the mix. After a tank or so you should get the balance back.

You need a new shift shaft and probably need a new shift lever due to the bad splines. You can try the JB Weld but I suggest that you go ahead and drill the lever an shaft then put in a cold roll split pin from the hardware store. You have nothing to loose since the shaft and the lever are already toast.

Oil is a grey colour in the engine of my yz 125 2001

Your bike is water cooled. Some of that water is leaking into the gear box. The cylinder gasket is the likely leak. I would let the shop take a look at it instead of trying to fix it yourself.

But be sure there is not an external source for the water. Do you wash the bike often? Ride the creek bed often? Leave the bike where the lawn sprinkler gets the bike wet? Leave it out in the rain? Change the oil and keep the bike dry. If the problem comes back then go see the dealer.

How do I change the oil seal on the water pump on at 02 YZ 125?

Hi,

This is a mechanical oil seal. In order to replace it, you will have to remove the right hand side engine cover. The seal is located in this cover.

If you are not an experienced mechanic then you should take your bike to a dealer.
NB use the genuine part for this bike.

Good luck

Jon
