Description

As your Hyosung 650 lives its life on the road, the internal rubber components of the carburettors eventually perish due to modern fuels. This leads to erratic idling, poor fuel economy, and difficult starting. Our 650cc rebuild kit is an essential maintenance item for both routine servicing and full restorations, providing the precision parts needed to get your vTwin running like new again.

💎 Performance with the Reliability!

We even include stainless steel bowl bolts to ensure your next service is as easy as this one.

💡 WHILE THE CARBS ARE OUT:
Check your vacuum lines! Cracked hoses cause weak fuel delivery. Upgrade to our [Braided Vacuum Hoses] for a 100% stable setup.

🔧 Installation Tips & Advice

Set Your Heights: When installing new float needles, always check your float height levels to factory specifications for perfect fueling.
Clean the Orifice: Ensure the needle seat is completely free of old fuel gum before pressing in the new assembly.
Stainless Swap: Ditch the original Phillips screws! Use the included stainless bolts for a much easier job the next time you need to clean your bowls.
