Primary Chain - Buell 2007 LIGHTNING Service Manual

HOME

PRIMARY CHAIN

GENERAL
Since the primary chain runs in lubricant, little service will be
required other than checking lubricant level and chain ten-
sion. If, through hard usage, the primary chain does become
worn and cannot be adjusted to within specifications, it must
be replaced. See 1.10 PRIMARY
An opening between the primary drive and transmission com-
partments allows the same lubricant supply to lubricate mov-
ing parts in both areas.
