The other issue with going to gear drives,after 2002 or so,they went from a forged crank to cast,and runout became more of an issue.I believe the spec is .002,anything over .003 causes noise from the gear drives.
On the later cranks,harley changed the spec for "acceptable" runout to .015.I think that's part of the reason gear drives aren't as popular as they once were.
