Honda UTV/ATV & Side by Side Throttle Bodies - Available at buywitchdoctors.com

Product Specifications: Genuine OEM Honda Shoulder Bolt, Part # 90021-MGZ-D02.

Keep your machine running like new with a genuine Honda Throttle Body paired with premium maintenance parts from buywitchdoctors.com. The throttle body controls how much air flows into the engine as you press the gas pedal or thumb throttle, and on fuel-injected Honda machines it works with the ECU, throttle position sensor, and idle air valve to deliver the right air-fuel mixture. A clean, properly working throttle body gives you smooth idle, crisp throttle response, easy starts, and strong, consistent power. Riders replace throttle bodies when the throttle plate or shaft wears and sticks, built-in sensors fail and trigger warning lights, the body cracks or the bore gets damaged, or dirt and carbon buildup cause rough idle, hesitation, and stalling.

Why Choose Genuine OEM Honda Parts?

Choosing original equipment manufacturer (OEM) parts ensures your vehicle maintains its factory-standard performance, reliability, and fuel efficiency. Genuine parts eliminate the guesswork of aftermarket alternatives, offering a seamless integration with your engine's configuration.

  • Exact-Fit Design: Matched to Honda's original bolt patterns, sealing surfaces, and dimensions for a leak-resistant fit.
  • Factory-Spec Quality: Built to the same standards as the parts installed on your machine at the factory.
  • Peace of Mind: Skip the trial and error of universal or aftermarket parts that may not seal or align correctly.

Premium Materials & Precision Engineering

Crafted to strict factory tolerances, these components utilize high-grade alloys and chemical-resistant seals. This specialized engineering withstands harsh off-road vibrations, extreme temperatures, and modern fuel additives, preventing premature wear and leaks. Honda throttle bodies are precision-machined to the factory bore size and airflow design, with sealed shafts and factory-calibrated sensors so they communicate accurately with your ECU.

Comprehensive Model Fitment (2015-Current)

This genuine OEM part is engineered for a wide range of Honda side-by-side (SxS) and all-terrain vehicles (ATV) built from 2015 to the current model year. Please verify your series matches below:

Utility Task Vehicles (UTVs / Side-by-Sides)

  • Pioneer Series: Pioneer 500, Pioneer 520, Pioneer 700, Pioneer 700-4, Pioneer 1000, Pioneer 1000-5, Pioneer 1000-6.
  • Talon Series: Talon 1000R, Talon 1000X, Talon 1000X-4 (including Fox Live Valve editions).

All-Terrain Vehicles (ATVs)

⚠️ IMPORTANT DISCLAIMER: Fitment can vary by production date and sub-model trim. Always verify your exact original equipment part number from your vehicle's schematic or consult a certified technician before finalizing your purchase to guarantee flawless compatibility.

Other Popular Parts & Secondary Accessories

  • PGM-FI Units: Genuine Honda PGM-FI units are the engine control modules that read the throttle body's sensors and control the idle air valve and fuel injection. If a new throttle body doesn't clear your idle or throttle fault, the PGM-FI unit or its wiring may be the cause.
  • Throttle Controls: Genuine Honda throttle controls include the thumb throttle or pedal housings and parts that connect your input to the throttle body. Replace sticky or worn throttle controls so the throttle opens smoothly and snaps back closed.
  • Airbox Components: Genuine Honda airbox components, including intake boots, ducts, and seals, deliver clean, filtered air to the throttle body. A cracked boot or loose clamp lets in unmetered air and dirt, so check these parts whenever you replace the throttle body.
  • Air Filters: Air filters trap dust and dirt before they reach the throttle body and engine. A clean, well-sealed filter keeps grit from scoring the throttle bore and helps your engine breathe and run its best.
  • Fuel Injectors: Genuine Honda fuel injectors spray a precise amount of fuel into the intake as air passes through the throttle body. A clogged or leaking injector can cause rough running that feels like a throttle body problem, so check both.
  • Fuel Additive / Treatment: Fuel additives and treatments help keep injectors, throttle bodies, and fuel systems clean and protect fuel during storage. Using them regularly can reduce varnish and carbon buildup that causes sticky throttles and rough idle.

Frequently Asked Questions (FAQs)

Q: How do I know if my throttle body needs to be replaced or just cleaned?
A: Common signs of throttle body trouble include rough or hunting idle, stalling, hesitation when you open the throttle, a sticking throttle, or a warning light or fault code. Start by checking for intake air leaks and inspecting the throttle body for carbon or dirt, since cleaning may fix minor buildup. If the throttle shaft is worn, the bore is damaged, or a built-in sensor has failed, replacement is usually needed. Follow your Honda service manual for cleaning, inspection, and any reset or relearn procedure after installation, and use the factory schematic to confirm the correct throttle body for your model.

Q: How do dust, water, and mud affect the throttle body?
A: Fine dust that gets past a dirty or poorly sealed air filter can coat the throttle plate and bore, causing sticking and rough idle. Water from deep crossings or pressure washing can get into the throttle body's electrical connectors and cause corrosion or faults. Mud packed around the intake can loosen clamps and boots. Keep your air filter clean and sealed, check intake boots and clamps after hard rides, and avoid spraying the throttle body and connectors with a pressure washer at close range.
