Authentic BAJAJ PULSAR 220 220F 220S UCAL CARBURETOR – Premium OEM Performance Carburetor
The BAJAJ PULSAR 220 220F 220S UCAL CARBURETOR is a precision-engineered fuel induction component manufactured specifically to replace degraded, clogged, or inefficient stock carburetors on Bajaj Pulsar 220, 220F and 220S carbureted models (2009 to 2017). Over thousands of kilometers of riding, road grime, ethanol fuel sedimentation, and mechanical slide wear degrade internal venturi tolerances, causing sluggish acceleration, hard starting, spark plug fouling, and erratic idling. Installing this authentic factory-calibrated carburetor assembly completely restores your engine’s original throttle response, fuel economy, and crisp throttle pickup.
Advanced Venturi Engineering and Fuel Metering
At the heart of the BAJAJ PULSAR 220 220F 220S UCAL CARBURETOR is a high-precision constant velocity venturi cast from premium die-cast zinc and aluminum alloy. Unlike cheap aftermarket replicas that suffer from porous casting walls and fluctuating vacuum pressures, this OEM-grade assembly maintains stable internal atmospheric differential pressures under all engine RPM ranges. The brass main jet, pilot jet, and emulsion needle are calibrated down to micro-millimeter tolerances to ensure an ideal stoichiometric air-fuel ratio (14.7:1), preventing either lean hesitation or rich cylinder washing.
Every internal component—including the fuel float, viton-tipped needle float valve, diaphragm return spring, and throttle valve slide—undergoes rigorous quality testing to ensure zero fuel overflow, rapid throttle slide return, and consistent vacuum sealing. Whether you are commuting through heavy urban stop-and-go traffic or cruising at sustained highway speeds, this carburetor maintains smooth, hesitation-free power delivery.
Key Technical Highlights and Features
- Direct Factory Fitment: Engineered as a drop-in replacement tailored for Bajaj Pulsar 220, 220F and 220S carbureted models (2009 to 2017), matching standard intake manifold spigots and air filter duct connections.
- Precision Brass Jetting: Factory calibrated pilot and main jets provide dependable cold-morning starting and strong mid-range torque without manual jet swaps.
- Viton-Tipped Float Valve: High-grade fuel needle ensures an airtight seal against the brass seat, completely eliminating fuel overflow and leaking.
- Corrosion-Resistant Alloy Body: Industrial-grade surface treatment withstands ethanol-blended petrol (E10/E20), humidity, and engine heat cycles without corrosion.
- Seamless Cable Integration: Integrated throttle and choke cable guide brackets ensure silky smooth cable operation and instant slide return.

Step-by-Step Installation Guidelines
For optimal reliability and peak engine efficiency, install the BAJAJ PULSAR 220 220F 220S UCAL CARBURETOR following standard workshop procedures:
- Safety Preparation: Turn off the motorcycle ignition and switch the petrol petcock to the OFF position. Disconnect the negative battery terminal.
- Drain Old Fuel: Position a fuel-safe container under the existing carburetor bowl and open the drain screw to safely evacuate residual petrol.
- Disconnect Cables and Ducts: Loosen the hose clamps securing the intake manifold spigot and airbox rubber duct. Carefully unhook the throttle cable and choke cable from the lever linkages.
- Remove Worn Assembly: Gently ease the old carburetor out from between the rubber boots, inspecting the intake manifold O-ring or insulator block for cracks or air leak traces.
- Install the New Assembly: Fit the brand new BAJAJ PULSAR 220 220F 220S UCAL CARBURETOR into position, ensuring both intake and air filter boots seat completely without pinches. Secure the clamps firmly to prevent vacuum leaks.
- Reconnect Cables: Attach the throttle cable and adjust the free-play adjuster to allow approximately 2 to 3mm of throttle grip slack. Reconnect the fuel line with a fresh spring clamp.
- Prime and Test Run: Turn the petrol petcock to ON and allow 60 seconds for the float bowl to fill. Start the engine, verify smooth idle speed, and fine-tune the idle air screw if necessary once the engine reaches normal operating temperature.
Frequently Asked Questions (FAQs)
1. How does replacing my worn carburetor improve bike performance?
Over time, internal jet orifices enlarge due to fuel erosion and throttle slides develop excessive clearance, causing incorrect air-fuel mixtures. Installing a brand new BAJAJ PULSAR 220 220F 220S UCAL CARBURETOR restores exact factory fuel metering, eliminating flat spots, improving fuel economy, and ensuring crisp throttle response.
2. Is this carburetor supplied pre-jetted and ready to run?
Yes. The BAJAJ PULSAR 220 220F 220S UCAL CARBURETOR comes fully assembled and factory flow-bench tested with stock pilot and main jets calibrated specifically for standard engines. In most standard installations, no jet modifications are needed beyond basic idle speed tuning.
3. Does this UCAL carburetor fit Bajaj Pulsar 220, 220F and 220S?
Yes, it features the factory 32mm large venturi assembly and automatic choke circuit engineered for carbureted Pulsar 220 models.
4. What should I check if my bike hesitates after installing a new carburetor?
Ensure that the intake manifold rubber clamp is completely airtight to eliminate vacuum leaks. Also inspect the petrol filter for clean fuel flow and ensure the air filter element is clean and properly seated.
5. How soon will my order be dispatched?
All carburetor orders placed on AUTOSS.IN are packed securely and dispatched within 24 to 48 hours via premium express courier services with end-to-end tracking provided to your registered email and mobile number.
