2025 Gas Gas MC 65 Carburetor Parts – OEM Mikuni Components

Premium carburetor components for the 2025 Gas Gas MC 65, engineered to deliver precise fuel metering and reliable performance. Whether you're rebuilding your stock Mikuni carburetor or fine-tuning for specific conditions, we stock the complete range of OEM jets, needles, and rebuild components.

What's Available

• Float Needle Valve & Seat – Controls fuel flow into the float bowl; critical for preventing flooding and maintaining consistent fuel level
• Jet Needle – Tapered needle that regulates fuel delivery from 1/4 to 3/4 throttle; factory spec for stock setup
• Main Jets (200–220) – Available in 5-unit increments (200, 205, 210, 215, 220) for precise high-throttle tuning based on altitude, temperature, and modifications
• Pilot Jets (17.5–22.5) – Fine-tune idle and low-throttle response; stock is typically 20, adjust for elevation or air filter changes

Start with OEM specs and adjust based on conditions. Higher elevation requires leaner jetting (smaller jets), while performance exhaust or air filter mods may require richer settings (larger jets). Pilot jets affect 0–1/4 throttle, needle position affects 1/4–3/4, and main jets control 3/4–full throttle.
