AUTOKAY Carburetor for Honda CRF50 XR50 Z50 — Stock-Size 32mm Center, 28mm Intake for 49–50cc

AUTOKAY's stock-size carburetor replaces worn units on Honda CRF50, XR50 and Z50-series 49cc bikes with a 32mm center-mount and 28mm intake for direct-fit performance.

This aftermarket carburetor is built to match the mounting and intake dimensions used on many small-displacement Honda minibikes and comparable Chinese pit bikes and go-karts. Designed for 49–50cc engines, it offers a straightforward swap when your original carb is clogged, leaking, or otherwise failing. The unit is intended as a practical replacement that restores throttle response and fuel delivery without extensive modification.

Will this carburetor fit my Honda Z50, XR50, or CRF50?

Yes — the AUTOKAY carb is made to the stock footprint used on many Honda 50cc minibikes and similar small engines. Check the engine mounting and intake measurements on your bike before ordering to confirm compatibility.

• Center mounting holes: 1 1/4" (32 mm) on-center
• Intake diameter where the airbox mounts: 28 mm
• Common fit: Honda Z50, Z50R, Z50A, XR50, CRF50 and many Chinese 49–50cc dirt bikes and go-karts

How easy is installation and what tools will I need?

Installation is straightforward for anyone familiar with small motorcycle maintenance and basic hand tools. You’ll remove the old carb, transfer any needed linkage and gaskets, then bolt the new AUTOKAY carb into place, making small adjustments to idle and mixture afterward.

• Basic tools: screwdrivers, pliers, metric sockets/wrenches
• Transfer choke/throttle cables and any vacuum lines if required
• Adjust idle and air/fuel mixture per engine behavior after install

What performance and maintenance differences should I expect?

This replacement matches factory sizing for predictable throttle response and stable idling on stock engines. Routine cleaning and occasional jet inspection keep it running well; it’s not a performance-upgrade carb but a reliable, OEM-style replacement.

• Works well on stock 49–50cc engines without re-jetting in most cases
• Provides consistent fuel delivery for everyday riding and light off-road use
• Servicing: accessible float bowl and jets for routine maintenance

Who is this for: riders, mechanics, and restorers who need a direct-fit replacement carburetor for small Honda minibikes or compatible Chinese dirt bikes and go-karts. Choose the AUTOKAY carburetor if you want a replacement sized to the original 32 mm center-mount and 28 mm intake, intended for 49–50cc engines, and assembled for straightforward installation and basic upkeep. If your project involves major engine tuning or big-bore upgrades, a dedicated performance carb or jetting changes may be required instead of this stock-size replacement.
