How much tranny fluid?

[jerry and sons]

I have a 03' yz 250 and need to change the tranny fluid, but I don't know the correct amount to refill.
Thanks for the help.

is it stamped on the filler side of case?
on my rm125 it is stamped on the clutch cover (650ml)

It's 750cm3 (ml) on my 04, it should be the same on the 03.

I could be wrong on this, but isn't 750ml the total amount of tranny fluid required? When you change the oil there is some oil left in the engine, so if you add in 750ml, you'll actually end up with more than 750ml in the tranny. I have an 02 YZ250. I open the weep hole and fill it til it leaks out. That's what my manual says to do.

The correct amount to refill my 04 YZ250 is 750ML, and the 03 engine is the same. Dont use the check hole to refill, because it starts to poor the oil out around 400ML , and thats too low.

I have been filling mine up with 700cc of oil.

Always error on the high side. My bike calls for 750 but I usually put in 800 at least. I know some guys that dump in a whole quart.

To much oil can cause as many problems as too little. Most likely, too much will cause a power loss due to the mechanicals swimming in the stuff. Drain it well and put in what it says. It'll work out about right. Remember, oil drains out more easily (and quickly) if it is warm. Also, loosening the filler plug will speed up the flow. In order to completely drain it, I usually go do something else while it drains.

So how come the service manuals say to fill it until oil starts dripping out of the check screw. Thats how I fill my bike. I will definately measure out the required amount and pour that in and see if when it starts to drip out of the check screw, how much oil is left over if any from the required amount.

just go with the screw on the clutch cover and you will be ok

I have been using a ratio rite for years. It really is the easiest way.
