38mm Performance Carburetor ? Custom Tuned With Jet Kit

Upgrade your 2-stroke with this 38mm high-performance flat-slide carburetor, custom tuned with a carefully selected baseline jetting setup for strong throttle response, smooth power delivery, and excellent high-RPM performance.

Unlike many aftermarket carburetors that arrive with generic factory jetting, each carburetor is custom jetted and set up before shipping to provide a much better starting point for your application.

Custom Tuned Baseline

Each carburetor is set up with a selected combination of main jet, pilot jet, needle position, and basic adjustments.

The 38mm size provides excellent airflow for larger-displacement and modified 2-stroke engines, making it a great performance upgrade for many dirt bikes, ATVs, and other 2-stroke applications.

Full Jet Kit Included

Additional main and pilot jets are included to allow further fine tuning for your particular engine and riding conditions.

Extra jets are especially useful when making changes such as:

• Aftermarket exhaust systems
• Ported cylinders
• Big-bore kits
• Performance reed valves
• High-flow intake systems
• Open airbox or aftermarket filters
• Fuel changes
• Temperature and seasonal changes
• Elevation changes

38mm High-Flow Performance

The larger 38mm bore provides increased airflow and fueling capability, making it especially well suited for performance-oriented 2-stroke engines.

A properly tuned 38mm carburetor can provide excellent midrange pull, high-RPM airflow, throttle response, and top-end performance.

• 125cc performance 2-strokes
• 200cc?220cc engines

Important Fitment Information

This is a universal aftermarket performance carburetor. Please verify carburetor dimensions, intake boot size, airbox/filter connection, and throttle cable requirements for your particular application before purchasing.

Some machines may require a different throttle cable, intake boot, airbox adapter, or other minor modifications.

Tuning Information

The installed jetting is intended to provide a strong starting baseline. Final jetting should always be checked for your specific engine and riding conditions.
