Can you gravity bleed our clutches?
 

Or is it not a good idea to do it that way when putting a new clutch and fluid in?

yes i did it yesterday, and it works, actually i used both variations, one being a bleed-o-matic brake bleeder to get air out of the lines, with the same exact results.. the clutch may seem to be stiffer if gravity bled i would say but i still didnt take it for a ride. no air means no air..
