        I think that all GS series bikes have rollers.

          By "rollers" does that mean the crank is on roller bearings?

          This site's article on the GS engines says they all have roller bearings except the 450.

            Thanks guys, that was what I was hoping since I don't have the book yet.

            Add a big yeap on the roller is a bearing on the crank.

              no they don't all have rollers, the 16 valve 750 went to a plain shell bearing, with high pressure oiling, the 1100 retained the rollers though, that's why one of the performance mods is to use the oil pump gears from a 16V 750

                From the microfiche it appears that the 400E has plain bearings since they offer an assortment of undersizes.
