For this pair of 40mm flat-slide carburetors, I’d make the description emphasize that they’re inspected/tuned as a matched pair while keeping the product completely generic.
40mm Performance Flat Slide Carburetor Pair – Custom Tuned + Extra Jets
Performance 40mm flat slide carburetor pair designed for high-performance 2-stroke twin-carb applications.
These are generic aftermarket carburetors intended for riders looking for increased airflow and a tunable performance setup without paying OEM carburetor pricing.
Unlike carburetors simply removed from the box and shipped, each carburetor is completely disassembled, inspected, checked, reassembled, and personally set up before shipping. Both carburetors are prepared together as a matched pair with baseline jetting installed.

EXTRA TUNING JETS INCLUDED
Additional main and pilot jets are supplied for fine-tuning.
Final jetting will depend on your specific setup, including engine displacement, porting, cylinders, exhaust, reeds, intake system, air filters, fuel, premix ratio, elevation, and temperature.
Send me your year, model, engine size, modifications, exhaust, reeds/intake setup, and approximate elevation when ordering. I can install a more application-specific baseline jetting setup before shipment.
PERFORMANCE APPLICATION
These 40mm carburetors are intended primarily for modified and high-performance 2-stroke engines where the larger bore and increased airflow are appropriate.
They may be suitable for custom twin-cylinder applications, including modified ATV and motorcycle engines, provided the intake and air-filter dimensions are compatible.
Because performance builds vary considerably, please compare the dimensions listed above with your existing carburetors, intake manifolds, and air-filter setup before ordering.
This listing should not be interpreted as guaranteeing direct bolt-on fitment for every custom engine combination.
GENERIC AFTERMARKET PRODUCT NOTICE
These are generic aftermarket performance carburetors.
They are not OEM carburetors and are not manufactured, sponsored, endorsed, or affiliated with Honda, Yamaha, Suzuki, Kawasaki, or any original carburetor manufacturer.
Any vehicle manufacturer or model names used in the listing are provided solely for fitment/application identification purposes.
PLEASE NOTE
Performance carburetors normally require final tuning after installation. The supplied jetting is intended to provide a strong starting point, but adjustments may be necessary based on your individual engine and riding conditions.
Questions about fitment or jetting? Send me your machine and engine setup before ordering and I’ll help determine whether this 40mm pair is appropriate for your application.
