Lifter Pin for this bushing is part 218-15STD or 218-15OS
**This can be used on 1921-1929 61" Twins.
**NOTE: 226-14 (Harley # DA738) has the smaller ID for the 61" pins and is 1.718” long. It was used for the 61” motors up to around 1920. At some point in the early/mid 20’s, Harley started using the larger cylinders for both the 74” and 61” motors. When they did that, they found that the additional ¼” of cylinder height on the 61” motors was causing the exhaust lifter pin & bushing to wear more, so they started making part 225-15 (replaces DA738) which was ¼” longer and kept the smaller ID for the 61” lifter pins.
