I didn't know they made Ulys in 04. I don't know a ton about uly's, but the xb12 only came out in 2004, so I didn't think the uly would've come out in the same year.
Anyway, the forks should fit in your triple clamps, but I think the Uly has a slightly longer travel fork, so it would be a little taller. That's not a fact though.
