Description
This small O-ring sits behind the oil strainer cap—if it is worn, cracked, or missing, your GV125S EFi can develop a slow but persistent oil leak at the bottom of the engine. Over time, engine heat and age degrade the rubber, making this a critical maintenance item. Replace it with this quality rubber seal to ensure a perfect fit and keep things dry and tidy underneath your bike.
💎 Inexpensive Engine Insurance
This is one of the cheapest and easiest ways to prevent slow oil leaks that could eventually lead to mess, stains, or, in rare cases, dangerously low oil levels. We ensure this part matches OEM specification to provide peace of mind that a cheap, unbranded alternative cannot offer.

If this O-ring is soft, your oil filter O-rings probably need changing too. Ensure a total leak-free service by grabbing our [GV125S Oil Filter Kit].
🔧 Install Tips & Guide
- Clean Surfaces: Wipe the O-ring groove and the engine case surface clean with a lint-free cloth before fitting the new seal.
- Lubricate: Apply a thin smear of fresh engine oil to the new O-ring. This prevents it from twisting or tearing during cap installation.
- Gentle Torque: Hand-tighten the cap first, then use a spanner or socket to torque lightly. Do not overtighten the cap or you risk stripping the engine case threads.
- Test: After installation, run the engine for 1–2 minutes and check the area for any signs of weeping or leaks.
