Intake Pipe O-RING (Inlet Boot Seals) x2 – GV125 GT125 RX125 GV250 GT250 Hyosung

Description

Between your engine and the intake pipe (aka inlet manifold) sits the crucial sealing O-ring. It ensures an airtight connection for proper engine and carburettor function and prevents harmful debris or air leaks that can damage your engine internals.

Over time, these O-rings lose elasticity, harden, and crack—much like uncooked pasta—especially after years of heat cycling. Even bikes as “young” as 5 years can suffer from degraded seals.

💎 Vital Air-Leak Prevention

When worn, symptoms include temperamental running, fluctuating idle, and lean mixtures that stress spark plugs and valves.

🔧 Installation Advice

Maintaining your intake pipe O-rings is a simple and cost-effective way to keep your Hyosung running smoothly:

• **The Clean-up:** Ensure the cylinder head surface and the manifold boot are perfectly clean of old rubber or grime before fitting the new rings.
• **Light Lube:** A tiny smear of silicone grease can help the O-ring seat perfectly without twisting during manifold assembly.
• **Don’t Over-tighten:** Snug the manifold bolts down evenly; over-tightening can warp the plastic boot, causing a fresh air leak.
