📜 Confirmed Fitment Guide

✅ FITS: Hyosung GV125S Bobber (V-Twin EFi model).
📅 YEARS: All S models from 2019+ onwards.
❌ WILL NOT FIT: Older pre-2019 carbureted GV125s, GT125, GT250, or any 300cc models.

💡 PRO-TIP:
If one injector is clogged, the other might not be far behind. Many mechanics choose to replace them as a balanced pair to maintain uniform fuel atomisation.

🔧 Install Tips

  • Safety First: Disconnect the battery and manage any residual fuel pressure carefully.
  • Prime the System: After installation, turn the ignition on and off several times (without starting the engine) to prime the fuel rail before the first start.
  • Get a Mechanic: If you are unsure about EFi diagnostics, allow a qualified garage to perform the installation.
