About This Product
Fine-tuning the ignition timing on a vintage Harley requires precise hardware, and this eccentric screw is a vital part of that process. Designed for 1947–1969 models with manual advance ignition, it fits 45CI Solo and Servi-Car models, 45 and 55CI KH and KR models, and 74 or 80CI Flatheads. It is also the correct fitment for 61CI Knucklehead, 74CI Panhead, and early Sportster engines. This Colony replacement part replaces OEM 30507-47A and allows for the accurate adjustment of the breaker points. Whether you are performing a routine tune-up or a full distributor rebuild, this eccentric screw ensures you can dial in your timing perfectly on your Big Twin or 45" motorcycle.
