CONSTRUCTION
The No. 1 valve rocker arm sub-assembly has been made thinner to achieve weight reduction. As a result, weight reduction has been achieved and friction has been reduced.
An oil delivery pipe is used to supply engine oil to the No. 1 valve rocker arm sub-assembly for lubrication. As a result, reliability is ensured by using a method where engine oil can be supplied from the upper portion of the camshaft to the sliding parts.
