Hey, does anyone know how much oil a 2002 yz125 takes? Also, can you use like Yamalube 20w-40 or do you have to use a transmission type of oil? CC's or quarts would be nice. Thanks:worthy:

Stay away from the auto oils the ones you can get at a shop are about the same price and better designed for the bike and clutch i use Maxima but almost all the mx brands are good. everyone has there own they use so you just have to pick one

In my sons 02 YZ125 we put 650CC in it and all we use is the Yamalube 20-40. Never had any problems with it.

Car oil will make your clutch slip, car oil is engineered to have more slippery quality's, or friction modifiers and will, I know for a fact make your clutch start slipping, motor cycle oils dont have the friction modifiers like car oils,

On the side of the engine case it will say like 850 or 750 stamped in the side case that means if you look on the side of the oil container you will see measurements in one hundreds, 850 is like 3/4 of a quart.

there isn't anything wrong with using SAE according to the book:prof:
Everybody has their own preference and some people just like paying more:banghead: then others for the same stuff with different brand names on them
oh and by the way no, i do not use 20w-40, i use 10w-30 like the book says

650cc is what the manual calls for.

But I put in 700cc just to be safe. It also helps cool the clutch a little.

You go right ahead and keep using that light weight 10/30 then, but answer this: If its so good to use standard 10/30 motor oil in a MX bike then why dont you see it bieng sold in ANY motorcycle shop out there? Thats probably because NO honda,yamaha, kawi, susuki shop out there will put 10/30 motor oil in your bike if you took it in to any shop for repairs or a oil change. And 10/30 Valvoline, Mobil ARE not that same as MX brands oil with a different label.

I hear of people using it but thats on them, ME ill stick to my MX oils as there not that much more expensive these days than oil from Kragen, Auto Zone <---- $3 and up for standard oil these days just bought some
