FASTENER TORQUE VALUES
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 Newton-meters.

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