BH-Motor Carburetor Choke Kit for Honda TRX300 1988-2000 — Plunger Starter Valve & Cable, Direct-Fit

This BH-Motor carburetor plunger choke starter valve and choke cable kit replaces OEM part 17950-HM5-850 to restore reliable cold starts on Honda TRX300 FourTrax 300 models (1988–2000).

If your Honda TRX300 stalls or struggles to start in cooler weather, the choke assembly can be the cause. This BH-Motor kit supplies the plunger-style starter valve and matching choke cable built to fit TRX300 and TRX300FW machines from 1988 through 2000, allowing you to return the carburetor to factory-style choke control without needing a full carburetor rebuild.

How does this kit improve starting performance?

Replacing a worn or seized starter valve and cable restores the choke’s ability to enrich the fuel mixture during cold starts. That helps the engine fire faster and idle more consistently until it warms up.

• Direct-fit replacement for factory choke components—no modification needed.
• Restores smooth plunger travel and solid cable movement for reliable engagement.
• Helps reduce repeated cranking and rough idling during initial startup.

Which model years and parts does this kit fit?

This set is designed specifically for Honda FourTrax TRX300 and TRX300FW ATVs from model years 1988 through 2000. It replaces the OEM part number 17950-HM5-850.

• Compatible models: Honda TRX300, TRX300FW (FourTrax 300).
• Correct fitment for 1988–2000 production years—check your engine bay for part number confirmation.
• OEM cross-reference: replaces 17950-HM5-850 for straightforward swap-in.

What should I expect during installation?

Installation is typically a straightforward swap: remove the old choke plunger and cable, then install the BH-Motor components in the same mounting points. Basic hand tools and minimal mechanic experience are enough for most DIYers.

• Standard hand tools required; no special press or puller normally needed.
• Follow the original routing for the cable to avoid binding or interference.
• Inspect the carb throat and linkage while installed; lubricate pivot points if necessary.

What are the kit’s construction and durability highlights?

BH-Motor supplies a replacement choke plunger and cable built to resist sticking and wear common on older ATVs. Materials and finish focus on corrosion resistance and smooth action under variable conditions.

• Plunger designed for smooth axial travel to ensure consistent choke engagement.
• Cable jacket protects the inner wire from grime and moisture for longer life.
• Quality fittings and end hardware sized to match original Honda mounting points.

Who is this for: This BH-Motor choke starter valve and cable kit is aimed at owners, hobby mechanics, and small shops maintaining late-80s to 2000 Honda TRX300 FourTrax ATVs. It's a practical, cost-effective part for restoring dependable cold-start behavior without replacing the entire carburetor, ideal for riders who want to keep a classic machine running reliably.
