TORQUE MASTER VALUES
GENERAL
Torque specifications for specific components are listed in
each section at the point of use. When converting to Newton-
meters, use the formulas given under the metric chart. For all
other steel fasteners, use the values listed in one of the
tables below. In the English table, torque figures are listed in
ft-lbs, except those marked with an asterisk (*), which are
listed in in-lbs. In the metric table, figures are listed in New-
ton-meters.

WARNING
The quality fasteners used on Buell motorcycles have
specific strength, finish and type requirements to per-
form properly in the assembly and the operating environ-
ment. Use only genuine Buell replacement fasteners
tightened to the proper torque. Substitution could cause
fastener failure, which could result in death or serious
injury.
