1986-2012 Sportster® & Buell - S&S Cycle

1986-2012 Sportster ® & Buell ®S&S ®FlywheelsFor 1986-'03 Sportster ® and 1994-'02 Buell ®S&S flywheels for 1986-’03 Sportster and Buell models feature a large tapered sprocketshaft and a large tapered pinion shaft. Since the stock flywheels for these engines donot have removable mainshafts, S&S engineers designed the pinion shaft with the samelarger, stronger taper as the sprocket shaft. Flywheels shown here are made to order.Parts forTwin Cam 96 /103 2007-2012Parts forTwin Cam 88 ®1999-2006S&S offers special flywheels for two-cylinder 1994-’02 Buell models. Although similarto flywheels for Sportster® models, these flywheels are knife edged and lightened. Thisspecial design offers these advantages:• Knife edging is a proven design used in race motors to make the flywheels "shed" oilmore quickly to reduce drag at high rpm.• Knife edging and lightening increases effective crankcase volume and reduces theflywheel assembly weight by 2-4 lbs. Increased crankcase volume results in betteroil control, effectively reducing friction and heat, as well as helping to control oilcarry over. Reduced weight results in faster revving and higher top rpm capability.• All S&S flywheels for Sportster and Buell models feature removable mainshafts foreasy 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 liftcams and stronger valve springs.Fitment• 1986-'03 Harley-Davidson® Sportster®• 1994-'02 Buell®• S&S SB-Series enginesFeatures 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• Assembled flywheels are dynamic balanced after assembly using our American-Hofmann® dynamic balancing machine unless otherwise specifiedOptions• Available in a wide variety of styles and strokes• Available balanced or unbalanced• Available assembled or unassembledKit Contents• Flywheels• Pinion shaft and sprocket shaft• Optional connecting rodsS&S® Made to Order flywheelsfor Harley-Davidson® Sportster® models7 7⁄8" Diameter (Stock)Year GroupStrokePart No.1986-'90 89" 45/16" 32-30611991-'03 89" 45/16" 32-30621986-'90 103" 5" 32-30631991-'03 103" 5" 32-3064Special Order Specify 32-3014**Special Order: Download the Special Order Form at sscycle.com/soformsCost of assembly or additional components is extra.No charge for balancing at the time of purchase.Year GoupS&S® Flywheelsfor 1986-'03 Harley-Davidson® Buell® modelsFlywheelStrokeFlywheelDiameterPartNumber1986-'03 35/8" 77/8" 32-30821986-'03 4" 77/8" 32-3083Special Order Specify Specify 32-3014**Special Order: Download the Special Order Form at sscycle.com/soformsTrying to identify an S&S® Flywheel?See Flywheel I.D.
