Working an 11 Hour Day at 80 Years Old!
This guide details a method for precisely relocating cam holes in a Sportster engine case, a technique developed by Dragon Man over 50 years. It involves using a custom fixture and a dial indicator to accurately find the center of existing holes, followed by drilling and boring to create new holes with a specific interference press fit. This method is presented as an alternative to using blueprints for complex engine modifications.
