The long proven 70cc Naraku cylinder kit is now also available in a V.2 version for D50B0 engines built up to 2018 (Euro3). The mould was adapted to the original D50B0 cylinder. The cylinder is painted in the factory cylinder silver colour and 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 up to 2018 with Euro3 emissions standard. Practically, the cylinder head also fits Euro4 models. However, for these Euro4 vehicles, the thread adapter NK103.78 must be used in addition.

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 to use a sports carburettor (19mm).
