There were many changes on the 07 Harleys, most of which have been received well, but complaints of a whining noise in fifth-gear, especially on dresser models, have surfaced. Bert Baker of Baker Drivetrain in Haslett, Michigan, has used his transmission expertise to address and eliminate this annoying issue for 2006 Dynas and all big-block 2007 H-D models. Quiet, helical-cut diamond ground gears (gears are cut at an angle versus H-D’s straight-cut spur gears) combined with 28% wider bearings, a 1/8” thick hardened steel bearing retainer plate (H-D uses snap rings), and a billet aluminum bearing door comprise the F6F kit which also includes new fasteners and a recalibration kit. The direct bolt-in assembly comes with a 5-year/50,000 mile warranty for $900. Stop your whining and check out at www.bakerdrivetrain.com or call 877-640-2004.
