Would switching to roller lifters alleviate this, George?

The motorcycling community is faced with the opposite problem - especially those of us whose bikes are wet clutch: Molydisulfide or Teflon added to the oil will cause clutch failure, and almost all "Energy Conserving" oils have one or both present.

From what I read, engines using roller lifter cams should be ok Fred.
