One day, riding a Harley FL to test his company 7-speed transmission Bert Baker noticed how hot it was running, especially in traffic. Then he found out that the 4-quart oil capacity was unchanged on touring models since 1993 at a time when the bikes were equipped with only a 80 cubic inch motor.
Taking a closer look at the stock oil pan he also discovered that the oil pickup and return in the front of the pan were within 2 inch of each other. So, he designed a wider new oil pan with a 5-quart capacity instead of 4, and improved oil circulation by installing the pickup in the rear and the return in the front. The Baker “Plus One Oil Pan” was born. With it installed testing showed that engine oil temperature went down 10 F on a 80 F day. This oil pan is a 2-piece aircraft grade 6061-T6 aluminum with multiple integral baffles eliminating the Harley plastic baffle. It is designed to accept the True-Track or Alloy Art TXR stabilizer systems. Fit 1993-2008 FLH applications. Info and sales at Baker Drivetrain Online Store.
