Product detail
Standards: 12V-Monkey (H Cylinder / R-10E)
■17R Stage +D Cylinder Head
Based on the stock head shape, large diameter valve intake: 26mm / exhaust: Adopt 22.5mm.
(12V Monkey stock valve diameter is intake: 19mm / exhaust: 16mm)
This is SP Takegawa's original cylinder head which adopts the most suitable valve pinching angle, combustion chamber shape and port shape for large diameter valves.
The port diameter of the stock head is 14mm for both intake and exhaust, while the port diameter of the 17R stage is 14mm for intake and exhaust: 24.5mm / exhaust: Larger diameter of 19mm.In addition, the adoption of a 3-dimensional port shape, combined with the larger diameter of the valve and port, makes it possible for more intake and exhaust gases to flow smoothly.
Valve: (Intake 26mm / Exhaust 22.5mm Valve stem shaft diameter 4.5mm)
The weight increase due to the larger diameter of the valve is kept to a minimum by the narrower stem shaft and waist machining.
Valve Springs: The single valve spring with unequal pitch (2-stage pitch) is adopted for optimum spring rate and suppresses surging at high rpm.
■Auto decompression camshaft
Auto decompression function: The engine can be started with a light kick force even on high compression and high displacement engines.
There are 3 types of camshafts, R-10E / R-15E / R-20E, and you can change the camshafts according to your application and enjoy the riding performance.
88cc / Scat 106cc / 106cc Kit Included Camshaft: R-10E
■Φ52H Cylinder (Aluminum steel sleeve cylinder)
It is the same design as the stock cylinder of the Cub engine in appearance (the height of the cylinder is different).
The M5 temperature sensor can be connected to the side of the cylinder, and the cylinder temperature can be measured by using SP Takegawa's compact LCD meter (with M5 temperature sensor) or by changing the sensor part of the thermometer to the M5 temperature sensor.
■Piston
The piston has a molybdenum coating on the skirt for better initial adhesion.
