💎 HYOSUNG GT650R GT650 GV650 | LARGE CARBURETTOR IGNITION COILS X2

Restore Carburettor Performance & V-Twin Spark. This pair of larger-style ignition coils is a direct replacement for early 650cc V-twin models. A reliable aftermarket solution to fix misfires, poor idling, or starting issues.

✅ Carby Specific: Tuned for the electrical resistance needed by carburettor systems.
🛠️ OEM-Style Fit: Matches the physical size and mounting pattern of the original large coils.
⚙️ Direct Swap: Uses standard HT leads and existing frame mounts.
📦 What’s Included: 2x Large Ignition Coils (Caps not included).

💡 CRITICAL FITMENT: ❌ **WILL NOT FIT EFI MODELS.** Also, physically check your existing coils—some later models use smaller coils, even on carby versions.

Description

Ignition coils on V-twins degrade over time due to heat and vibration. On these early carburettor models, a weak coil results in rough running and poor power delivery. These aftermarket coils are built to match the original specifications and physical size, providing a reliable spark and keeping these legacy 650cc Hyosungs running strong. Hyosung made running changes, so check your frame clearance and existing coil size before ordering to ensure fitment.

💎 Reliable Spark for Classic 650s

Quality components engineered to provide reliable performance and longevity, justifying their use in demanding environments.

Carb Specific Resistance Optimised for non-EFI systems.	Durable Housing Resists weather and vibration.
Easy to Install Uses existing mounts and HT leads.	Fixes Misfires Restores smooth power delivery.

📜 Confirmed Fitment Guide (Carburettor Models Only)

✅ FITS: GT650, GT650R, GV650 Aquila/Avitar (Carburettor Models Only).
📅 YEARS: Primarily early-to-mid 2000s models (Confirm physical size before ordering).
❌ WILL NOT FIT: Any EFI (Fuel Injected) models or bikes using the physically smaller ignition coils.

💡 RECOMMENDED PAIRING:
The original spark plug caps are often weak. Upgrade to durable **NGK HT Leads & Spark Plug Caps** to guarantee a strong, reliable spark. View NGK Caps here.

🔧 Install Tips

Verify Physical Size: Measure your existing coil or check frame clearance against our photos. Hyosung used two sizes over the years.
Download Manual: Consult your free workshop manual available in our forums for exact installation procedures and torque settings.
Test the Old Coils: Use a multimeter to test the resistance of your old coils before replacing them to confirm they are indeed faulty.
