Piston Ring 38 mm for Original Cylinder (Without Catalytic Converter)

Are you looking for the optimal sealing for your engine? This high-quality piston ring with a 38 mm diameter is the perfect choice for your original cylinder without a catalytic converter. It ensures that the compression stays where it belongs, allowing your moped or scooter to zip through the streets with full power again.

Since the piston ring is precisely tuned to the dimensions of the original cylinder, you benefit from excellent fit accuracy. An intact ring is crucial to avoid power losses and minimize wear on the cylinder wall. If you notice that your vehicle struggles uphill or starts poorly, a replacement is often the simplest and most effective solution.

Installation and Maintenance Tips

• Be cautious during installation: Piston rings are brittle. Stretch the ring only as much as necessary to slide it over the piston skirt into the groove. A piston ring pliers can be very helpful in this process.

• Cleanliness is a must: Thoroughly clean the groove in the piston of oil carbon residues before inserting the new ring. Only then can it move freely and seal optimally.

• Observe installation direction: Pay attention to the markings (usually a small letter or "Top"). This side must always face the cylinder head.

• Lubrication: Wet the ring and the cylinder bore with a bit of two-stroke oil before assembly to prevent a dry first start.
