Hello

How much oil do you run i your yxf 250 19?

Stock is 290cc and 0.47 springs

But when I try racetech calculator they said 340cc oil and 0.44 fork springs for my weight 82kg without gear.

I run 290-300cc in all my KYB forks now and would definitely stay with the stock springs before going down to .44kg. Also, if you do change springs make sure they are 497mm to have the correct installed preload. Many companies are selling the YZ springs anywhere from 492-500mm and that's a massive swing in preload.
