I have a 140mm 08 marzocchi XC600 tst2 and i have it set to 65 lbs which is over the max of 60. I weigh 250 w/ gear. When seated i have 20% sag, when standing i have around 50% and i never get the full travel.. It seems to hydrolock with around 25mm travel to go. When riding normal XC it doesnt bottom out but anything more then 2feet is a different story. What can i do to fix this?
