Revitalize your Harley-Davidson's performance with the Twin Power CV Carburetor Recalibration Kit. Specifically designed for 1990-2006 Big Twin and Sportster XL models equipped with the Keihin CV (Constant Velocity) carburetor, this kit addresses common issues like throttle flat spots, hesitation, backfiring, and poor throttle response. It's the perfect solution for optimizing your engine's fuel delivery and achieving smoother, more powerful acceleration.
The Keihin CV carburetor, while reliable, can sometimes benefit from fine-tuning, especially after modifications or simply due to age. This Twin Power kit provides the precise adjustments needed to bring your engine back to its peak performance. Experience a noticeable improvement in how your Harley runs, from initial startup to full throttle. Whether you're cruising the highway or navigating city streets, this kit ensures your ride is as smooth and powerful as it can be.
