How does this carburetor improve throttle response?

The VM22 26mm carburetor supplies a tuned airflow path and a calibrated jetting baseline suited to 110–140cc small engines, which helps deliver crisper midrange and smoother acceleration. When installed correctly and paired with proper jetting adjustments, riders will notice more predictable throttle behavior across the rev range.

• 26mm manifold outlet with 22mm inner bore for balanced airflow.
• Pre-configured pilot and main jet sizes for common small-bike setups.
• Throttle linkage compatible with many XR50/CRF70/KLX-style configurations.
• Included mounting parts simplify swap-out from worn carb units.

Will this VM22 fit my 110cc, 125cc or 140cc engine?

This carburetor is made for 110–140cc Lifan, YX and Zongshen clone engines and fits many popular pit bike models including XR50-style and CRF70 conversions. The critical fit points are the manifold outlet diameter and bolt spacing—measure your existing carb to confirm compatibility before purchase.

• Manifold outlet diameter: 26mm (22mm inner bore).
• Manifold bolt eye-to-eye spacing: 48mm, bolt diameter 6.5mm.
• Compatible with BBR, Apollo, Thumpstar, Braaap, Atomic, DHZ, SSR engine platforms.
• Comes with mounting hardware for a straightforward replacement.

What adjustments or maintenance are needed after installation?

After fitting the VM22, you should set the idle, adjust the air/fuel mixture via the pilot screw, and fine-tune jetting for altitude or performance changes. Regular maintenance—cleaning the float bowl, checking needle seat, and inspecting jets—keeps the carburetor working reliably.

• Initial idle and mixture screw adjustments recommended.
• Main jet tuning may be required for different exhausts or air filters.
• Periodically clean float bowl and jets to prevent clogging.
• Replace gaskets or needle/seat if you notice flooding or fuel leaks.

How easy is installation for a home mechanic?

Installation is straightforward for anyone familiar with small-engine carb swaps; the VM22 uses common bolt patterns and throttle linkages so most home mechanics can fit it with basic tools. The package includes the parts shown in product images to simplify the swap, but double-check hose sizes and throttle cable ends before starting.

• Basic tools and a service manual make the process quicker.
• Keep shop rags and a fuel-safe container handy when disconnecting lines.
• Verify throttle return spring and choke linkage operate freely.
• Test ride and re-check idle/mix after a short run-in period.

Who is this for: The LEIMO KPARTS VM22 26mm carburetor is aimed at riders, mechanics and hobbyists repairing or upgrading 110cc–140cc pit and mini dirt bikes that use Lifan, YX, Zongshen or similar small engines. It’s suitable for those who need an affordable, drop-in replacement to restore reliable fueling, as well as tuners who want a platform that accepts modest jetting and throttle adjustments. If you’re unsure about fitment, measure your existing carburetor’s manifold outlet and bolt spacing to confirm compatibility before ordering.
