Product Description
With the latest V.2 Cylinder kit series from NARAKU, we can offer a more advanced product.
As a 4 stroke cylinder is effectively just a hole, the emphasis on technological development was placed on the piston and compression.
The piston has 2 additional CNC-machined oil grooves in the piston skirt, which collects engine oil to lubricate the cylinder bore and improve characteristics in extreme circumstances. The molybdenum coating aids the crucial running-in period, 2 oil recesses and a groove at each bearing point ensure the gudgeon pin is adequately lubricated.
The compression ratio has been specially calibrated to the requirements of everyday running. Naraku’s high quality and very good power delivery cap off this cylinder kit putting it up there with the best.
The kit can be used with the original carburettor, but upjetting will be required by around 8-10%.
Supplied as shown in the image, original head can be used.
