ok here's the real story
I took in my dorado to get an oil change beacuse I though Dorado's were high maintenance forks. So they looked at it and said the oil was ok, so they proceded to take it appart and clean it. -_- So that's cool as long as they know what they are doing. I get it back I hear a little oil with air but not much durring travel so I guess its ok. Now comes the DH race were TRavel on your Fork is being used 100 %. The dent is close to the 2 & 1/2 inches of last travel. So when my fork passes the 2, 1/2 " of travel the dent on the damper shaft passes the o-ring that separates the oil from the air in the fork(cartridge assembly). The cartridge assembly is were the TCP dampening valving and oil. So When the nice circular o-ring seal is broken by the dent on the damper shaft oil spurts out from the cartridge and air goes in when the travel starts to go back to 7". So basicly this dent is making oil come out and air go in. I NEVER had this problem before I gave it to them but one thing that bothered me is that when they gave it back to me they said that the damper shaft had a minor scratch on it and its nothing to worry about. Being so stupid I had no idea it would affect the performance of a great fork. So its their word against mine, I think they busted my fork and they said it was all ready there. So depending on what Manitou tech guys say when they see my fork will determine if I cough up the $$$ for the part. So that's the deal.
