🔧 Installation Tips & Advice
- Before installing, thoroughly clean the carburettor body and all parts with a carb cleaner spray to ensure no dirt or residue affects performance.
- Inspect all old gaskets and seals; replace them with the new O-rings in this kit to prevent future leaks and air ingress.
- Take care when installing the float needle assembly — ensure the float moves freely and that the needle seats properly to avoid fuel overflow or starvation.
- Check for any signs of wear or damage on the carburettor slide, jets, and pilot screws and clean or replace as necessary.
- Once rebuilt, allow your carburettor to settle for a few minutes before starting the bike to ensure proper fuel flow.
- If you notice rough idling or poor throttle response after installation, consult the detailed tuning guides available on our forums.
- Always test ride in a safe environment to confirm smooth throttle response and no fuel leaks before regular riding.
Regular carb maintenance and using genuine quality parts like this rebuild kit can significantly extend your bike’s life and keep it running at its best. Don’t let old, worn carburettor parts hold your Hyosung back — upgrade today!

When upsetting my GV125 this kit proved absolutely invaluable. Had I not purchased this we would still be struggling with rusty bolts and perished rubber seals. Thanks Marcel.

Came to Spain very quickly. Excellent kit. Spain being a bit naughty with customs since Brexit, or it may be because I use a private post box! Not bad though as I had €100 of parts and they only charged €10.
