[Description]
■Features of Super Head 4V+R (1 Cam 4 Valve)
Compared to the SP Takegawa Super Head +R's large diameter 2 valves, the SP Takegawa Super Head +R has 2 intake valves and 2 exhaust valves, which increases the valve curtain area and improves the intake and exhaust efficiency more than the large diameter 2 valves.In addition, the head shape was designed to balance the center plug, valve pinching angle, combustion chamber shape, and port shape in order to achieve high power output and sustained output characteristics in the high RPM range, which is the biggest feature of the Super Head.
By adopting 1 cam and 4 valves, it was possible to make it as light and compact as possible, and at the same time, it condensed the performance as the strongest SOHC head.
New shape super head 4 valve + R body
The round shape of the cylinder head suits the Monkey style and enhances the custom image of the vehicle.
Each head cover is made of die-cast and barrel polished to give a beautiful appearance to the cylinder head.
Valve Features
Valve Spring
The use of unequal pitch prevents surging at high RPM.
IN / EX Port Features
The port diameter is optimized for SP Takegawa's 3D shaped manifold.In addition, by installing it together with the 3-dimensionally shaped manifold, it enables a smooth intake effect from the carburetor to the combustion chamber without resistance, and the performance of the cylinder head can be maximized.
Adoption of roller rocker arm
By adopting the roller rocker arm, the output performance of the Super Head +R is maximized and the output in the mid to high speed range is increased and the output in the high rpm range is maintained, which is the characteristic of the roller rocker arm.The roller rocker arm reduces the frictional resistance with the camshaft that occurs with the slipper type rocker arm (stock part type), and the roller bearing in the rocker arm follows the cam profile smoothly from low to high RPM.
M8 Spark Plug
The M8 spark plug was adopted in conjunction with the optimum valve pinching angle and the compactness of the head due to the 4-valve system.
■Hollow camshaft
The camshaft is supported by ball bearings at both ends to reduce frictional resistance in the camshaft journal.Optional camshafts are available in addition to the included camshafts, allowing you to change the camshafts to suit your application and enjoy the performance of your vehicle.
■Cylinder / Piston
Aluminum steel sleeve cylinder is adopted.The cylinder is equipped with a temperature sensor as standard.You can measure the cylinder temperature by purchasing SP Takegawa's thermometer built-in meter or thermometer.
For 88cc H Cylinder: M5 Temperature Sensor
Piston
The piston skirt is coated with molybdenum for better initial adhesion.
