Just bought a used bike fitted with an 05 or 06 Bomber 66 RC, to add heavier, more DH oreinted ride to my little stable o' bikes. Problem is I haven't owned a Marzo. fork in years and I'm bangin my head trying to get some sag out of the thing

I've got zero air in it and can't get even 2" of sag out of a 7" stantion. I come in about 210 lbs.

I'm thinking overfilled oil? Does Marzo offer a heavy spring that could have been put in aftermarket?

Suggestions for a guy who knows nuthing about the 66 before I start tearing things apart and/or throwing cash at it.
