Short version: 130 lbs will be absolutely fine on the factory bars.
Long version: I have an '01 Sport that I'm driving cross-country. After a couple of false starts I have a modified Yakima LoadWarrior setup that carries 300 lbs, though if I was doing it over I would probably go with Con-Ferr or the like -- I'd rather have three mounting points per side.
As far as the factory bars, for the '97-'01 model years they're officially rated for 150 pounds. I originally tried putting 260 pounds on them (well, I eyeballed it and it didn't *look* like more than 150
), and astonishingly that got me from northern California to Texas. It might never have failed at all had I stayed on pavement, but after a couple of good trail bumps in Big Bend the rear bar finally buckled and I got myself two dimples in the roof.
My next step was to get the rain gutter towers and cross-bars from Yakima. That worked for a little while, except (a) the entire basket kept sliding over to the right side of the roof, no matter how hard I cinched down the plastic mounts, (b) the rear bar bent severely over time (mostly on the road) and the brackets were almost touching the roof again, and (c) the towers wouldn't hold the bars securely enough -- I had to keep tightening them. I think it was the black plastic coating that their bars come with.
At this point I went to a metal supply house and got two lengths of 1-1/8" pipe with 1/4" walls -- beefy stuff. The 1-1/8" pipe turns out to be exactly what the Yakima bars were, so I didn't have to do anything to the towers. I got the pipes galvanized to prevent rust and give them a little more grip, and topped it off by gluing slices of 1/8"-thick rubber mat to the top and bottom mount clips on the basket.
It's been about a month since I did all that -- so far no problems. I've also added some 20-30 lbs and the heavier pipes add ~15 lbs as well. I haven't done any heavy wheeling yet (I will this week, will update), but I did a bit of dune-hopping and it didn't seem to complain. If I look closely along the rain gutters I can see just a shade of deformation right around where the towers come in, but IMO not enough to be concerned about (and the metal actually bends slightly UPwards, not down).
I'll post pics when I have a chance. HTH...
