Does anybody know if the 02 monsters had sealed cartridges or not? Just wondering because I did an oil change to a heavier oil but I did't notice a difference in how it rode.

Sorry for being a suspension newbie, but how would you change out oil in a sealed cartridge setup?

The only marzocchis that have a sealed cartridge are the "TST" damped marathons and AM series. The earliest they made those forks (AM1) was 2005.
