Swingarm - Buell S1 Lightning Workshop Manual

MODEL YEAR CHANGE
All 1997 model year motorcycles use a revised swingarm
pivot assembly. The modifications allow preload to be
adjusted without using the

used on 1996 models. This new part changes the
ARM, ASSEMBLY and SWINGARM, INSTALLATION
dures in the 1996 manual.
