Naraku 150cc performance cylinder kit suitable for Yamaha X-Max, WR, YZF-R 125cc and other 125cc mopeds with YI-3 engine.
To ensure an exact fit and power output we recommend the matching Naraku cylinder head NK600.75 which is also designed for Ø60mm bore and displacement. The original cylinder head can be used, but it is mandatory to correct the cylinder squish edge by spacing with appropriate foot gaskets!
The carburetor or the injection system should be retuned (eg with Malossi Force Master)!
Delivery as shown with all gaskets, pistons and small parts necessary for assembly.AI-translation
