Moose Racing Carburetor Repair Kit 1003-0812 — Yamaha YZ250F 2008-2009

Product Description

If your Yamaha YZ250F is suffering from hard starting, erratic idling, or poor throttle response, it is likely time for a carburetor overhaul. The Moose Racing Carburetor Repair Kit 1003-0812 provides everything needed to return your fuel system to factory-spec performance.

Unlike standard repair kits, Moose components use NBR rubber for all O-rings and gaskets. This specialized material is engineered for superior resistance to the ethanol additives found in today's pump fuels, preventing the hardening and swelling that lead to future leaks. This kit includes all essential items, including jets, needles, mixture screws, float bowl screws, and a new float valve needle and seat.

Frequently Asked Questions

Q: Should I clean my carb body before installing this kit?
A: Absolutely. This kit replaces the wearable components, but if the carburetor body itself is clogged with gum or varnish from old fuel, the new parts won't fix the issue. A thorough ultrasonic cleaning or a high-quality carb cleaner bath is highly recommended.

Q: Why does NBR material matter for my fuel system?
A: Modern pump gas contains ethanol, which is corrosive to standard rubber. NBR (Nitrile Butadiene Rubber) is specifically formulated to resist these chemicals, ensuring your O-rings don't swell or break down over time.

Expert Pro-Tip: When replacing your jets, be extremely careful not to overtighten them. Carburetor threads are typically made of soft brass and are very easy to strip. Snug them down gently—they do not need massive torque to seal.
