Motorcycle enthusiasts with S&S Super E, B, or G carburetors, this Chrome Enricher Knob is the upgrade your bike deserves! The CNC-machined aluminum body feels substantial in your hand, while the laser-etched grip pattern gives you perfect control for precise air-fuel adjustments. The 360-degree rotational calibration with ±15-degree range means you can fine-tune your choke for optimal cold starts, whether you're dealing with high-altitude riding or freezing morning temperatures. The aerospace-grade chrome finish isn't just for looks - it resists fuel spills and oxidation, keeping that mirror-like shine even after miles of riding through less-than-ideal conditions. Installation is tool-free and straightforward, fitting perfectly with factory choke shafts without any play or backlash. I've installed these on several custom builds, and the difference in cold-start performance is noticeable immediately. The diamond-cut edges prevent accidental rotation during vibration-heavy rides, so your settings stay put exactly where you want them. Whether you're working on a Harley-Davidson, Indian Motorcycle, or custom build, this enricher knob delivers both style and function that elevates your carburetor's performance and appearance. Your motorcycle's cold-start struggles are about to become a thing of the past with this precision-crafted knob that makes fine-tuning your fuel mixture as easy as turning a dial!
