I thought the bike was setup from factory for someone 180lbs., this calculator is showing a big difference?

180-200. You should be fine once you set the sag and play with the rebound and compression. What Woodracer250 has listed for you is 100% exact to your weight. But with companies like mx-tech, race-tech, pro-action, ect, they're much more precise.

180-200.

I run stock springs and I'm just fine w/ them. I was on the edge, but I'm glad I didn't drop the coin for something I didn't need. :p
