Information on product safety
With the latest V.2 cylinder kit series from NARAKU, we can offer a product that has been further developed in many details

.The piston has 2 additional CNC-milled oil grooves in the piston skirt, in which engine oil collects to improve the lubrication at the cylinder bore and the properties in emergency running. Especially for the sensitive running-in phase of the cylinder, the piston was provided with an extra molybdenum coating. Through 2 oil holes and 1 groove in each of the bearing points of the piston pin, this itself is better lubricated.

The compression ratio has been specially adapted to the needs of everyday use. A usual high manufacturing quality of NARAKU and a very good power delivery characterize this 47mm cylinder.

The kit can be operated with the original carburetor, but we recommend to adjust the main jet. The kit includes all parts necessary for assembly
