Fuel Injection Throttle Body Assembly for Bajaj Pulsar 150CC, Pulsar 150 Twin Disc BS6 - SKU: DH121260

Precision Air-Flow Butterfly Valve: Ensures linear, predictable air intake response from closed-throttle idle to wide-open acceleration.

Direct OEM Harness & Sensor Integration: Engineered under part code DH121260 for drop-in sensor and fuel-injector rail alignment without custom modifications.

High-Grade Cast Alloy Body: Thermal-resistant lightweight metal construction prevents warping under hot engine bay soak conditions.

Optimized Bore & Bypass Port: Calibrated airflow channels maintain steady cold-start fast idle and smooth deceleration transition.

ECU Telemetry Sync: Restores factory voltage feedback curves for throttle position and manifold pressure tracking.

Restore factory air-fuel metering precision and eliminate throttle lag, rough idling, or acceleration stumbles with the Fuel Injection Throttle Body Assembly for Bajaj Pulsar 150CC & Pulsar 150 Twin Disc BS6 (SKU: DH121260). As the core heart of your BS6 fuel-injected induction system, a carbon-fouled, sensor-worn, or mechanically bound throttle body destroys fuel economy and ride driveability. Engineered to exact factory tolerances, SKU DH121260 integrates smooth butterfly valve actuation, responsive TPS/IAC signal alignment, and durable alloy housing for seamless ECU communication.

A failing or gummed-up BS6 throttle body causes frustrating engine stunting, fluctuating RPM drops at stoplights, and poor combustion efficiency. Upgrading to the genuine-spec DH121260 throttle body brings back factory-fresh linear acceleration, clean emission behavior, and total touring confidence.

Recognizing Throttle Body Failure / Contamination Symptoms

Rough, Hunting, or Stalling Idle: RPM fluctuates erratically at a standstill or the bike dies when pulling in the clutch and rolling off the throttle.

Bogging / Hesitation on Quick Throttle Twist: Delayed or jerky power delivery when snapping open the throttle from cruising speeds.

Check Engine Light (MIL) / FI Fault Codes: ECU triggers sensor-range or TPS correlation error codes linked to the induction assembly.

Carbon Varnish Build-up: Visible heavy black gum/carbon rings sealing the butterfly edge inside the bore, restricting base idle air control.

Maintenance & Installation Best Practices

Periodic Throttle Bore Cleaning: Clean the butterfly valve perimeter using sensor-safe throttle body cleaner every 10,000–15,000 km (avoid harsh carburetor sprays that degrade seal coatings).

Reset TPS / Idle Adaptation: Perform a diagnostic ECU throttle position calibration/reset procedure post-installation if required by Bajaj diagnostic protocol.

Inspect Vacuum & Breather Hoses: Ensure all auxiliary vacuum lines and breather connections around part DH121260 are clamped airtight to prevent unmeasured lean-air anomalies.
