17R-Stage+D Bore Up Kit 106cc Scut 12V-Monkey (Scut Cylinder/R-10E)

Improvements to the port and fin shape from the conventional R-stage +D, along with the adoption of a new profile camshaft, further increase output in the high RPM range!!
Based on the normal head shape, it uses large-diameter valves: Intake: 26mm / Exhaust: 22.5mm.
(12V Monkey normal valve diameters are Intake: 19mm / Exhaust: 16mm)
This is a Takegawa original cylinder head that incorporates optimal valve angles, combustion chamber shape, and port shape to match the large-diameter valves.
The port diameter of the normal head is 14mm for both intake and exhaust, while the 17R stage port diameter is larger, with intake at 24.5mm and exhaust at 19mm.
