Naraku 70cc Cylinder Kit V.2 - Gilera D.N.A 50 2000-2007

The primary benefit is a significant increase in engine power and acceleration due to the larger displacement.

It is highly recommended to adjust the carburetor jetting by approximately 7-10% and a 17.5-19mm sports carburetor is advised for optimal performance and engine health.

While you can use the original cylinder head, a dedicated 70cc cylinder head is recommended for the best performance results, as it is designed to match the increased cylinder volume.

Follow the manufacturer's recommended break-in period (typically 300-500 km). During this time, vary your engine speed and avoid sustained high RPMs or full throttle. This allows the piston and cylinder walls to properly seat.

No, it is specifically designed for models from 2000-2007 with water-cooled Piaggio engines (pentagonal type, manufactured from 1997 onwards). Always verify your engine type.

The molybdenum coating helps to protect both the piston and the cylinder walls during the initial break-in period, reducing friction and wear.

Yes, the Naraku cylinder is designed to be compatible with both series (stock) and sports exhaust systems.

Carburetor jetting is likely too lean. Increase the main jet size by 7-10% or more, check for air leaks in the intake system, and ensure the air filter is clean.

Check coolant level and flow. Ensure the exhaust system is not overly restrictive and the air-fuel mixture is correct. Overheating can also occur if the break-in procedure was not followed correctly.

Verify all components are correctly installed. Ensure the exhaust system is not blocked and the carburetor is properly jetted for the larger displacement. A restricted exhaust or incorrect fueling will cause power loss.

Ensure you are varying throttle and engine speed, avoiding prolonged periods at high RPM. If you experience pinging or knocking, the fuel mixture may be too lean or the timing may be off. Check carburetor settings.
