Description
Whether you are executing a routine engine service or executing a full top-to-bottom restoration on the workbench, this comprehensive aftermarket Hyosung carb repair kit is an absolute must-have hardware bundle. As your bike handles regular road miles, the internal rubber seals inside the fuel bowls eventually dry out, flatten, and perish due to continuous contact with modern fuels. This degradation leads directly to irregular engine speed patterns, bad fuel economy, and highly difficult starting behaviors on cold mornings. This targeted maintenance set replaces your worn parts with precision-cut components, allowing you to restore factory-smooth fueling and crisp throttle response without having to order an expensive complete original factory assembly.
This custom-curated package matches the exact internal dimensions of your standard Mikuni fuel bodies to guarantee first-time operational reliability. Every box arrives completely loaded to service both front and rear assemblies simultaneously, packing fresh intermediate float bowl gaskets, uprated inlet needle pins, precision seats, and crucial mixture screw seals. Furthermore, we include eight unrustable stainless steel hex head screws as a free upgrade bonus. Swapping out your soft original cross head screws removes the common risk of rounded heads, ensuring that any future clean-out or maintenance project remains entirely straightforward on your workbench.

💡 REBUILD BUNDLE ACCESSORY SUGGESTION: If you find your original fuel bowl screws are already seized or heavily rounded from age, ensure you have enough hardware to finish your rebuild. Complete your custom styling project by pairing this overhaul pack with our expanded standalone casing bolt kits to tidy up your external fuel body accents nicely.
🔧 Installation Tips & Advice
Follow these simple workbench steps to ensure a perfect fluid rebuild and avoid common assembly pitfalls:
- Cleanliness is Completely Crucial: Always blast the interior passages and aluminum casting recesses thoroughly with a dedicated solvent spray before inserting your new parts. Trapping any microscopic speck of old rust crust inside will instantly jam your fresh needle settings.
- Ensure Total Free Float Movement: Take extra care when sliding the float needle assembly onto its brass bracket posts on the bench. Check manually that the float moves up and down without sticking, and confirm the needle seats completely straight to avoid fuel overflow or top-end starvation bugs.
- Consult Technical Help Forums for Fine Tuning: If you experience rough idling patterns or a lazy throttle response after buttoning your covers back down, do not guess your fuel height levels. Look over the detailed tuning guides and synchronization manuals written by other owners inside our community archives: View the full service guides on the forums.

It’s a very nice kit that includes what you need. I especially like that it comes with new screws!

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.

Upsetting should read Upjetting…….. Maybe the two are interchangeable!😁

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.
