Oil leakage caused by stripped drain plug threads can be resolved by using a larger tap to rethread, installing a thread insert, and reinstalling the drain plug. Oil seepage due to cracks in the crankcase can be repaired using riveting or aluminum repair compound.

Dealing with oil leaks on the CFMoto 250SR starts with identifying the root cause. My bike had the same issue before, which turned out to be due to either a deteriorated engine oil pan gasket or loose bolts. First, I wiped the engine surface clean with a paper towel, then started the engine for a few minutes to observe where fresh oil stains emerged—most commonly around the bottom joints or oil filter. If you're doing it yourself, try buying a new gasket or tightening the bolts; don't ignore small leaks, as they can escalate into bigger problems. If you're not confident in your DIY skills, visit a reputable repair shop—they have the tools and professional testing equipment to inspect the oil pressure system. Avoid using second-hand parts to save money, as they can affect longevity. Regular maintenance can prevent leaks—check the gasket's seal every time you change the oil, making it a habit saves hassle in the long run. Otherwise, accumulated oil can contaminate the electrical circuits.
