Twin Power Bendix Carburetor Rebuild Kit - 492925

The Twin Power Bendix Carburetor Rebuild Kit (Part #492925) is a complete overhaul solution designed specifically for pre-1980 Panhead and Shovelhead Harley-Davidson Big Twin motorcycles equipped with Bendix-style carburetors. If your vintage Harley is suffering from rough idle, hesitation on acceleration, or fuel delivery issues, this rebuild kit from Twin Power gives you everything needed to restore like-new carburetor performance without sourcing individual components piecemeal. It's a purpose-built kit for classic Harley restorers, weekend riders, and performance-minded wrenchers who want dependable fueling from an era-correct carburetor.

Key Features & Benefits

• Includes Accelerator Pump: The accelerator pump is one of the most wear-prone components in a Bendix carb. Having a replacement included in this kit means you can address hesitation and bog on throttle tip-in — one of the most common complaints on aged Bendix carburetors — without a separate parts order.
• Idle Mixture Screw Included: A worn or leaking idle mixture screw causes erratic low-speed fueling and poor off-idle response. This kit includes a replacement screw so you can dial in mixture settings on a fresh, properly sealing component.
• All Necessary Seals for Factory Sealing: The kit bundles every gasket and seal needed for a full rebuild, eliminating the guesswork of figuring out which seals to order separately and ensuring no potential leak point is left unaddressed.
• Precision Components for Smooth Throttle Response: Twin Power designs these components to deliver consistent fuel delivery and smooth throttle response — critical on a vintage engine where carburetor condition directly impacts rideability and reliability.
• Restores Early Big Twin Performance: Rather than replacing the entire carburetor, this rebuild kit allows you to revive a serviceable Bendix carb to like-new function — preserving the period-correct look and feel of your classic Harley at a fraction of replacement cost.
• Not CARB Legal — Purpose-Built for Off-Highway/Race/Vintage Use: This product is not CARB legal and is not for sale in California, which is important to know before ordering. Outside California, it is a straightforward, bolt-in rebuild solution.
