What is the correct way to set the fork oil height on ktm 200 forks,01 model. The manual says 150mm, but it does not give detailed instructions. They have holes in the top of the inner tubes like KYB, so do I fill them to the top to allow oil to fill the space between the tubes or just fill the inner tube like on older showa forks. Also any suggestions to make these forks work better in the rocks and roots for a 145lb. rider? I'm about out of options myself.
