Valve Clearance: IN 0.04, EX 0.07 Stem Diameter: Φ5.5
*Dax 70 is a japanese model only.
The diameter of the face is increased to 25 on the intake side and 22 on the exhaust side to improve the volumetric efficiency of the combustion chamber and to achieve higher output and higher rpm. Both IN and EX are nitrocarburized to increase the surface elevation and improve initial blending. In addition, we have succeeded in reducing the cost by mass production, which makes the product more affordable.
Points of Attention
* If there may be an instruction manual included, it will be written in Japanese.
