I just picked up a 2006 Marzocchi 66 light. Decided to open it up and check the oil levels even though the previous owner said it was just serviced. I found the oil level quite low on the left spring side. The service manual lists volume's : 205cc right, 70cc left. So I decided to call Marz. and ask for an oil height " Disregard the publised spec's , 60mm from the top both sides . I asked for air pressure spec's and was told "15 psi max spring side and 50 psi RC2 leg". I aked why was there a difference ? "When the spring is installed in the left leg the oil level rises - needs less air, smaller chamber. So my next question why not equal the oil heights so there is similar air volume progression and similar air pressures can be used ? Thanks.
