And also make sure you're using the right lube as well. They aren't all the same.
I use the Dye lube (or Shocker lube since it's the same thing), and others swear by Slick Honey, Marmalade, or Lurker's Lube. Really any Dow 33 lubricant will work about the same.
Just make sure you don't use Dow 55 as it swells orings. If you are using it and not aware of it, that would cause the bolt stick you're experiencing.
