KCFJW2025 Carburetor Rebuild Kit for S&S Super E – Complete seals, gaskets & diaphragms for Harley applications

KCFJW2025 Carburetor Rebuild Kit is a ready-to-install replacement set of seals, gaskets, and components designed to restore an S&S Super E (Super E gas carb) for Harley‑Davidson applications.

This rebuild kit delivers the common seals, O-rings, diaphragms, and small metal parts you need to service an S&S-style Super E carburetor. Manufactured from metal and rubber materials chosen for durability, the set is intended to match the typical wear items found in Super E carburetors and simplify a routine refresh without buying a complete carburetor. Before ordering, verify compatibility with your motorcycle model and compare the provided photos to your existing carb parts.

What exactly is included in this rebuild kit and how complete is it?

The kit contains one full carburetor rebuild set with the most common replacement pieces used when overhauling an S&S Super E carb. It focuses on small parts that wear over time and are essential for proper sealing and function.

• Seals, O-rings, and gaskets sized for Super E carburetors
• Diaphragm and rubber components for metering and vacuum sections
• Small metal fittings and a 90° swivel piece where required
• Single kit packaged as shown in photos (1 Pc per package)

How do I install the KCFJW2025 rebuild kit on my Super E carb?

Installation is intended to be achievable with basic hand tools like screwdrivers and tweezers, but it requires careful disassembly and attention to sealing orientation. Turn off fuel and power, clean the carb thoroughly, then replace worn parts one at a time while noting their positions.

• Disconnect fuel and power before beginning work
• Use a clean workspace and small trays to keep parts organized
• Replace gaskets and diaphragms exactly as removed to maintain sealing
• After reassembly, start the engine and confirm proper idle and throttle response

Will this kit fit my Harley‑Davidson or my existing Super E carburetor?

The rebuild set is made to replace worn parts on Super E gas carburetors commonly fitted to Harley‑Davidson models. Compatibility depends on the carburetor revision and part numbers; compare the kit's components and the included part number reference to your carb for a match.

• Fits S&S Super E style carburetors used on many Harley installs
• Check part reference numbers (e.g., 11-2923, 499619) against your carb
• Inspect photos and part shapes before purchasing to confirm fit
• Not a full carb replacement — intended for wear-component refresh

What materials and durability can I expect from this replacement kit?

Parts in the kit are manufactured from metal and rubber, selected for routine reliability in fuel-system environments. These components are practical for standard maintenance cycles, though life span depends on riding conditions and fuel quality.

• Metal fittings for mechanical strength and corrosion resistance
• Rubber seals and diaphragms engineered for fuel compatibility
• Designed for routine servicing rather than heavy duty overhaul
• Easy to install with common hand tools for most mechanically inclined riders

Who this is for: This rebuild kit is best for Harley‑Davidson owners or mechanics who want to refurbish an S&S Super E carburetor by replacing commonly worn seals, diaphragms, and fittings without purchasing a full replacement carb. It suits DIY riders comfortable with carb disassembly or shops performing routine carb service. Verify compatibility with your bike and review the item images carefully to ensure the parts match your existing carburetor components.
