FLYWHEELS FOR 1986–'99 HARLEY-DAVIDSON ® SPORTSTER ® AND 1994–'97 BUELL ® MODELS FITMENT • 1986–'99 Harley-Davidson® Sportster® • 1994–'97 Buell® • S&S SB-Series engines FEATURES AND BENEFITS • CNC machined from heat-treated, closed die, steel forging • Stronger than cast iron or late style steel flywheels

• 5-piece design—easily rebuilt with standard flywheel fixtures and tools • Unassembled balanced flywheels are balanced by the static method FLYWHEEL ASSEMBLIES FOR 1994–‘97 BUELL® MODELS S&S flywheels for two-cylinder 1994–’97 Buell models. Although similar to flywheels for Sportster® models, these flywheels are knife edged and lightened. This design offers these advantages: • Knife edging is a proven design used in race motors to make the flywheels "shed" oil more quickly to reduce drag at high rpm. • Knife edging and lightening increases effective crankcase volume and reduces the flywheel assembly weight by 2–4 lbs. Increased crankcase volume results in better oil control, effectively reducing friction and heat, as well as helping to control oil carry over. Reduced weight results in faster revving and higher top rpm capability. • All S&S flywheels for Sportster and Buell models feature removable mainshafts for easy rebuilding. In addition, the S&S pinion shaft is the 1986–’87 splined design, which is much stronger than the stock pinion shaft, allowing the use of higher lift cams and stronger valve springs. OPTIONS • Stock replacement or stroker flywheels for high performance upgrade • Available in a wide variety of styles and strokes • Available balanced or unbalanced • Available assembled or unassembled by special order KIT CONTENTS • Flywheels • Pinion shaft and sprocket shaft • Optional connecting rods

REPLACEMENT PARTS: SEE PAGE 285

Lightened flywheels are not recommended for Sportster models with solid mounted engines due to increased vibration and loss of low rpm torque. S&S pinion shafts for 1986–’03 Sportster® models are the splined 1986–’87 style. Pinion and oil pump drive gears in 1988–’03 models must be replaced with early style gears. See page 262 Complete S&S Flywheel assemblies will fit up to 1999 model year engines. However, the flywheels are compatible with stock crankpins up to 1999 only. Stock stroke flywheels are balanced to stock weight pistons These flywheels will not fit 1998–up Buell® models.
