..i have two other drive boss bushings that are still well within spec on their I.D., and they fit nicely on the shaft...
..imma machine one to 1.475", for a good spare..and one to 1.450".....
..THAT one imma try out when i get a new malossi variator, coupled with a gates 729 belt....
..i think the OEM moveing drive face's roller ramp profile is maxed out...
..i noted hard roller markings on the outside edges of the ramps...
..the malossi has a longer ramp profile, which lets the rollers travel further out, which causes the belt to ride higher on the pulley at top speed...
..the malossi is also a few mm greater in diameter than oem....
..every mm is a good one!!!
peace
