MOOSE OFFROAD 400-1278-PU Replacement Carburetor — Honda XR650L (1993-2012)

MOOSE OFFROAD — Turn-Key Performance, Direct OEM Replacement, and Reliable Fuel Delivery for the Honda XR650L

Restore the legendary reliability of your Big Red Pig with the MOOSE OFFROAD 400-1278-PU Replacement Carburetor. Engineered specifically for the air-cooled Honda XR650L, this fully assembled, ready-to-install unit is the perfect solution for riders facing gummed-up internals, erratic idling, or damaged factory housings. As a high-performance, economical alternative to the prohibitively expensive OEM carburetor, this kit allows you to refresh your entire fueling system in one simple step.

This direct replacement carburetor is designed to interface seamlessly with your stock Honda throttle and choke cables, maintaining the factory feel and operation you’re used to. Each unit comes pre-jetted for standard factory configurations to get you back on the dirt faster. However, because the XR650L is a favorite for modifications like high-flow air filters and aftermarket exhausts, minor tuning of the fuel mixture may be necessary to achieve the perfect balance of power and efficiency for your specific setup and altitude.

• Ready to Install: Fully assembled unit designed to bolt directly onto the intake manifold using factory cables.
• Economical Performance: Provides factory-level fuel atomization and throttle response at a fraction of the dealer cost.
• Complete System Refresh: Replaces the entire carburetor, including floats, needles, and jets, eliminating the need for tedious rebuilds.
• Pre-Jetted: Setup for standard 650cc operation to simplify the installation process and reduce downtime.
• Durable Off-Road Build: Precision-cast alloys and a professional silver/black finish designed to handle heat and heavy vibrations.

Moto-House MX Pro Tip:

The Honda XR650L is a bulletproof machine, but its CV carburetor is sensitive to debris and fuel varnish. The MOOSE OFFROAD 400-1278-PU is the most effective way to solve "lean" conditions or bogging issues that a simple cleaning can't fix. When installing this new carb, we highly recommend inspecting your intake boot for cracks and replacing your fuel filter to ensure a clean supply of gas. If you ride at high altitudes or have done the "Dave’s Mods" airbox surgery, remember to check your plug color to see if a simple needle adjustment or jet swap is needed for your specific climate.
