Description
When the throttle slides wear out, the jet needle often needs replacement too. Our aftermarket jet needle kit goes beyond a standard maintenance part; it’s a performance upgrade. The added adjustment grooves empower you, the owner, to adjust your fuel mixture precisely—whether compensating for airflow upgrades (like our DNA/BMC filters) or correcting a stock rich/lean setting. This is essential for life on the road and getting the most from your Hyosung.
💎 Precision Tuning, Better Performance
Use the included E-ring and extra grooves to dial in your mixture for better starts and a punchier mid-range.

🔧 Install Tips
- Start in the Middle: If unsure which groove to use, start with the E-ring in the middle position (3rd groove down).
- Mixture Reading: Check your spark plugs after a run. A dark brown colour indicates perfect tuning. Lowest groove = richest setting.
- Professional Help: If in doubt about tuning or installation, have a qualified mechanic perform the fitment.
