TVS Genuine Specification Throttle Slide Valve & Metering Pin Kit for Jupiter 110 (Part: CSPTJ01)

Precision-Finished Slide Piston: Smooth exterior surface coating reduces friction against the carburetor bore, preventing binding or lag during throttle twists.

Calibrated Metering Pin (Needle): Accurately regulates fuel flow through the main jet across varying throttle openings for optimal combustion efficiency.

Direct OEM Fitment: Matches factory dimensions, linkage slots, and spring tension (Part #CSPTJ01) for a drop-in installation without custom adjustments.

Durable Alloy & Composite Construction: Built to resist wear from continuous vacuum movement and chemical exposure to modern ethanol-blended fuels.

Balanced Return Spring: Ensures snappy, reliable return to closed-idle position when you release the twist grip.

Restore smooth throttle control, precise air-fuel metering, and effortless acceleration to your scooter with the Carburetor Slide with Pin Assembly for TVS Jupiter 110 (SKU: CSPTJ01). Serving as a vital component in your carburetor's variable-venturi system, a worn, scored, or sticking slide valve compromises throttle linearity and fuel efficiency. Engineered to exact factory specifications, SKU CSPTJ01 features a precision-finished sliding piston, responsive return spring, and calibrated metering pin to ensure seamless throttle translation from idle to wide-open acceleration.

A scored or binding carburetor slide leads to frustrating throttle sticking, uneven idling, and sluggish fuel response that ruins your daily commute. Upgrading to the CSPTJ01 carburetor slide and pin assembly brings back crisp acceleration, reliable idle stability, and factory-smooth scooter performance.

Recognizing Carburetor Slide Wear and Malfunction

Sticky or Delayed Throttle Return: The twist grip feels heavy, or engine RPMs hang high for a few seconds after you roll off the throttle because the slide is binding in its bore.

Hesitation on Acceleration: A noticeable flat spot, bogging, or choking sensation when you suddenly twist the throttle open from an idle stop.

Erratic Idling / Fluctuating RPM: Inconsistent idle speed caused by air leaking past a worn slide or incorrect pin seating.

Visible Scoring or Grooves: Fine scratches or deep vertical wear marks visible on the outer walls of the old slide piston upon inspection.

Maintenance & Installation Best Practices

Clean Carburetor Body Bore: Thoroughly clean the inner sliding walls of the carburetor throat using carb cleaner and a lint-free cloth before dropping in SKU CSPTJ01 to remove old varnish.

Inspect Diaphragm and Rubber Seals: Check the vacuum diaphragm (if applicable to your specific sub-model variant) for pinholes or tears while servicing the slide assembly.

Do Not Force Linkage: Ensure the metering pin drops cleanly into the main jet opening without bending; never force the slide down if it encounters resistance during reassembly.
