NOTES:
• Stock crankcases need to be machined to accept new cylinders. S&S can provide this service for you!
• S&S Easy Start Cams can save you money – no need to buy compression releases or S&S rocker covers.
• 2008-up touring models with electronic throttle control require Screamin' Eagle® 58mm throttle body and Harley-Davidson® race tuner or Dynojet® Power Vision flash tuner, see page
1-61 for more details.
• Main Bearing Note: S&S flywheel assemblies for 1999-'12 big twin engines are designed for use with Timken® style sprocket shaft bearings. They will fit directly in stock Harley-
Davidson® 1999-’02 crankcases and in all S&S crankcases for Twin Cam 88® engines with no modifications. S&S does not produce a set of flywheels that is a direct replacement for the
2003 and later big twin engines. Stock 2003 and later engines use the same roller type bearing for the sprocket shaft that is used on the pinion shaft. However, S&S flywheels may be
used in 2003 and later engines with the installation of the Harley-Davidson® bearing kit #24004-03B. These crankcases use a roller type bearing for the sprocket shaft. Verify that the
bearing kit contains the 24604-00D or 24607-07 sprocket shaft bearing. Do not use a 24604-00, 24604-00A, 24604-00B or 24604-00C bearing.
• S&S recommends retrofitting a Timken bearing (31-4013) into 2003-'12 model crankcases with the use of a Timken sleeve, Screamin' Eagle #34822-08 or Jim's #956. A charging
system spacer for 1999-'02 model year is also required. S&S can provide this service for you.
• Fuel injection tuning is required. S&S offers fuel injection tuning solutions starting on page1-59.
