Description
Let’s be honest — the stock float bowl bolts on many Hyosung carburettors are a notorious weak point. Made from cheap mild steel, they seize up due to rust, corrosion, or just general weather exposure.
This makes routine carburettor servicing frustrating and often damaging, as owners are forced to use worn screwdrivers or risk stripping the bolt heads. This UK-Made Stainless Steel Bolt Upgrade Kit is the perfect, professional solution.

🔧 Installation Tips
Installation is a simple swap, but correct procedure ensures longevity:
- **The Right Tool:** Use an Allen key or proper hex tool bit for a confident fit. The new HEX socket design eliminates the slipping issues common with the stock Phillips/JIS screws.
- **Clean First:** Clean the area around the bolts before removal to avoid dirt falling into the float bowl.
- **Anti-Seize/Thread Prep:** When installing the new stainless bolts, apply a small amount of anti-seize compound to the threads. This ensures easy removal next time.
- **Torque Specs:** Torque bolts to the manufacturer’s specification. These are small bolts on a soft aluminium carb body; do not overtighten!
