I just did the forks on my 250k- The manual says they should have around 570ml /side I got a total of 600 odd out of both forks. Ive always used ATF-- put 10psi a side -- $11/litre they feel fine to me  :D

Just did my 250k forks with 10w oil at 170mm from the top of the sliders with no spring - as per manual.
And I thought the forks would be almost the same as Barbie as they are both 43mm , but where Barbie had a normal bolt to the dampening rod the 250k had a bolt with holes and an internal spring? What is this for?

There is a rubber bung right below the bottom of the hex in those bolts Rosey and that is the compression adjuster. Straight slotted screw.

Thanks Fred .
Would there be any advantage in putting the compression adjuster bolt in Barbie's forks? That's if they would screw in of course, and I think the fork legs are different

If I had to guess, I would say they wouldn't fit, because the damper rods would be different as well as the fork slider.
