Cylinder kit NARAKU V.2 70cc incl. cylinder head for Piaggio / Derbi D50B Euro4

The long-proven 70cc Naraku cylinder kit is now also available in a V.2 version for D50B engines built from 2018 (Euro4). The mould was adapted to the original D50B cylinder. The cylinder is painted in the factory cylinder anthracite colour and is therefore hardly distinguishable from the original.
Naraku offers this kit exclusively with a 70cc cylinder head exactly matched to the cylinder. The resulting compression ratio makes the kit a daily driver with rich torque and excellent acceleration values. High revs and associated noise levels were deliberately not in the foreground with this sports cylinder.
The cylinder head thread matches temperature sensors built from 2018 with Euro4 emissions standard.
This Naraku cylinder kit is recommended for both standard and sports exhaust systems. If the original carburettor remains installed, it is highly advisable to increase the carburettor jetting by about 7-10% (guideline). We recommend using a sports carburettor (19mm).
