Product Detail
Specification
12V Monkey (R-10E / X section connecting rod reinforced crank R type)[Product Configuration]
・Head Kit
・Camshaft
・Cylinder Kit
・Crankshaft Kit
Description
The port and fin shape has been improved from the previous R stage +D and a new profile camshaft has been adopted for even more power at higher RPMs!!!
50mm stroke crankshaft with X-shaped connecting rods
■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 three types of camshafts, R-10E, R-15E and R-20E, and you can change them according to your application and enjoy the riding performance.
88cc / scat 106cc / 106cc kit supplied camshaft: R-10E
■Φ52H cylinder (aluminum steel sleeve cylinder) and piston
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.
The piston has a molybdenum coating on the skirt for better initial adhesion.
■Reinforced crankshaft (2-point crankshaft)
X-shaped connecting rods
Forging material is machined, and an X-shaped cross section is adopted.
It is lightweight and strong enough, and its buckling stress diffusion and torsional rigidity are greatly improved.
Surface shot finish.
Strengthening the Journal Department
A special bearing with a larger inner diameter is used for the crankshaft journal bearing.
As a result, the shaft diameter of the journal section, where the stress on the crankshaft is concentrated, can be increased from 20mm to 22mm to increase the strength of the shaft.
