6-16 2006 Buell Lightning: Drive/Transmission
HOME
PRIMARY CHAIN 6.5
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 CHAIN .
An opening between the primary drive and transmission com-
partments allows the same lubricant supply to lubricate mov-
ing parts in both areas.
