K&N (DNA/BMC) Air Filter + Upgrade Carb Jets Kit – Hyosung GT125R GT125

Description

A popular tuning combination for 125cc carbs! Standard factory paper filters are heavily restrictive and degrade quickly under weather exposure. When combined with original lean fueling setups, your engine is left choked for both air and fuel. This Stage 1 performance pack addresses that maintenance reality by vastly expanding your intake airflow and correcting the air-fuel ratio directly out of the box. Sourcing this premium aftermarket Hyosung GT125 stage 1 kit is a true performance investment for your restoration project. The immediate result is smoother power delivery across the rev range, cleaner cold morning starts, and a crisp throttle response.

We use premium European-made DNA or BMC elements inside this package due to their superior structural build quality, easily washable mesh construction, and excellent filtration density. The included stainless hex hardware adds reliable rust protection and a clean polished finish to your engine bay area during your intake rebuild, ensuring your next routine maintenance check remains completely hassle-free.

🔧 Expert Installation & Gearing Notes

• Why Main Jets Are Critical: Drawing in a larger volume of cold air means you must expand your fuel metering size to match. Running a performance element on stock factory nozzles causes the engine to run dangerously lean at high speeds, which overheats valves and scores pistons. We include the exact proven sizes needed to balance this specific filter mesh.
• Always Use Sized JIS Tooling: When unbolting your float chambers to swap the brass main nozzles, ensure you utilize a proper Japanese Industrial Standard cross head driver tool. Western cross bits will slide right out under torque and instantly strip the soft factory screw slots. We provide unrustable stainless freebie bolts in this pack to keep future maintenance projects easy.
• Washable Lifetime Design: Your new DNA or BMC element is fully reusable for life. When the mesh becomes loaded with road dust, simply wash the fibers clean with specialized cleaner, allow it to dry thoroughly, apply a very light coat of filter oil, and refit.
