These high quality gears are carefully machined, heat-treated and then finish ground. If the stock gear is unmarked and the size is unknown we recommend that you order a gear in the middle of the tolerance range. These sizes were used more often and should provide adequate gear clearance under most circumstances. Note: Gear sizes for 1954 thru 1989 are listed from biggest to smallest. This color coding sequence is identical to stock Harley-Davidson color coding for the late 1977 thru 1989 models. For the 1954 thru early 1977 models there was only one size available from Harley-Davidson, Jims and S&S issued their own color coding for these pinion gears. Sizes are given measured over .105" pins. 2085 PINION GEARS FOR BIG TWIN 750083 Green, OEM 24059-91 These S&S pinion gears are the stock design as used in 1991 thru 1999 Sportster models. You can also use these when you want to install 1991 thru 1999 style stock or aftermarket cams in a 2000 to present Sportster or Buell. 2086 PINION GEARS FOR 5 SPEED SPORTSTER MODELS 750076 Red, OEM 24057-86 750077 White, OEM 24058-86 S&S provides high quality 1986-'87 style pinion Sportster pinion gears for use with the S&S Evolution style pinion shafts used in S&S flywheel assemblies. These are the splined style pinion shafts as S&S does not produce the 1988 thru 1990 style keyed pinion shaft for Evolution style Sportster engines. S&S feels the keyed design is not as strong, and that the splined pinion shafts are preferable for high performance applications. Also fit stock 1986 thru 1987 flywheels. 2082 PINION GEARS FOR 4 SPEED SPORTSTER MODELS 751349 Fits 1990-1992 Evolution Big Twin, USA made (OEM 24043-90) 290565 Fits 1993-2000 Evolution Big Twin, Genuine Zodiac (OEM 24043-93) 751350 Fits 1993-2000 Evolution Big Twin, V-Twin Mfg.
