The V-Twin Part Number 74478DZ V-Fire Overhead Valve Auto Advance Distributor Zinc is designed for classic Harley Davidson overhead valve Big Twin models from 1936 to 1945. This distributor features an auto-advance mechanism, making it an ideal upgrade for vintage systems or for ground-up restorations. Its robust construction and precise timing capabilities ensure reliable performance, whether you're restoring a vintage motorcycle or building a custom project. The distributor does not include the point lead wire, which should be ordered separately, allowing for tailored wiring setups to fit your specific configuration. Installation requires removing the front cylinder head, and the distributor's design accommodates a snap throttle using any handlebar setup, eliminating the need for a separate left-hand spark advance control. The unit's update points plate permits wire exit towards the rear, facilitating cleaner wiring routes and easier maintenance. The distributor is compatible with various accessory items such as chrome and parkerized screws and lead wires, which are recommended for optimal installation and performance. The points should be adjusted at cylinder top dead center, with the front lobes opening and closing the points correctly for proper timing. For ease of adjustment, points are mounted on the front side, and both lobes must operate correctly to ensure consistent spark timing across cylinders. This distributor is ideal for use with the recommended Blue Streak Ignition Point Set and other ignition components, providing a reliable, vintage-style ignition system with modern enhancements. Crafted in Taiwan, this distributor offers a durable solution for restoring or customizing your Harley Davidson Big Twin motorcycle. Proper installation and maintenance will ensure your engine runs smoothly, with precise ignition timing critical for peak performance and longevity. Whether upgrading an existing system or building from scratch, this distributor offers compatibility and performance tailored for vintage Harley Davidson models.
