*The camshafts and rocker arms are special products.Always use in combination. *This product cannot be used in combination with products made by other manufacturers. *There is a possibility that the rocker arm may interfere with the cylinder head due to its shape or error.In this case, it is necessary to modify the interfering part.
[Product Description] High camshaft, roller rocker arm and valve spring set for 125cc to large displacement high end tuning vehicles. The cam profile is calculated based on the data accumulated from many races, and the needle roller type rocker arm is used to reduce friction. Furthermore, the use of unequal pitch valve springs prevents surging at high RPM. This is a camshaft kit with data.
[Features] The rocker arm is about 10% lighter than the first generation model. Lighter 13mm roller bearings are used to reduce losses.
It was developed for FI vehicles (CYGNUS X4 / BWS 125 Type 2) and is designed to maximize the engine characteristics in the rpm range before the limiter is activated.
In combination with the special roller rocker arm, the friction loss is reduced and the power loss in the mid to low speed range is improved.
By increasing the camshaft base circle to 21mm, the acceleration and stabilization of valve movement and the valve jump problem are improved compared to the general small diameter base circle camshaft.
The optional reinforced tappet adjustment bolts are designed for increased lift and improved durability.
