Superhead 4V+R Combo Kit 181cc (Silver) (Big Throttle Body)

【Takegawa 01-05-0608 Super Head 4V+R Combo Kit 181cc (Silver) (Big Throttle Body) Monkey 125 Bike Injection Controller TAKEGAWA】
■Product Description
Super Head 4V+R (1 Cam 4 Valve)
Achieved easy-to-handle output characteristics and high output with the adoption of a 1-cam 4-valve head!
The combo kit includes the Super Head 4V+R bore up kit 181cc, FI CON TYPE-X, big throttle body kit, large capacity injector, and spark plug.

【Super Head 4V+R (1 Cam 4 Valve)】
By having two intake and two exhaust valves, the valve curtain area is expanded, achieving high intake and exhaust efficiency.
The original head shape is designed with a balance of center plug, valve angle, combustion chamber shape, and port shape for 4 valves, achieving high output that cannot be obtained with normal heads. The combustion chamber is finished with high precision by NC processing.

・SOHC class-leading intake and exhaust efficiency
Valve diameter IN: 25mm x 2 / EX: 21.5mm x 2
Valve stem shaft diameter: 4.5mm for both IN and EX
Adoption of unequal pitch valve springs prevents surging at high RPMs.
The cylinder head surface is black painted.
An inspection breather cover is included, so by purchasing a separate oil catch tank kit, the internal pressure of the engine can be released.
The inspection breather cover, inspection cover, and L. cylinder head side cover are made of aluminum die-cast with barrel polishing.

・Forged aluminum roller rocker arm
Reduces frictional resistance with the camshaft and achieves smooth operation! Maximizes output and maintains output in the mid-to-high speed range.

【Camshaft/Cylinder/Piston】
・Auto decompression camshaft
Achieves smooth engine starting without straining the cell motor.

・All-aluminum ceramic plated cylinder adopted.
Bore diameter: 63mm Stroke 57.9mm (stock)
Ceramic plated cylinders offer excellent durability, airtightness, and heat dissipation.
The cylinder is equipped with an oil outlet for an oil cooler, so by purchasing a separate oil cooler kit, oil temperature rise can be suppressed.
The cylinder surface uses unpainted "silver".

・Aluminum cast piston
High-compression specification with a compression ratio of 12.5:1.
Piston designed for high performance and durability.
The piston top is finished with high precision by NC processing.

【Valve/Valve Spring/Rocker Arm/Camshaft】
・Valve diameter IN: 25mm x 2 / EX: 21.5mm x 2
Valve stem shaft diameter: 4.5mm for both IN and EX

・Unequal pitch valve spring
Prevents surging at high RPMs.

・Adopts forged aluminum roller rocker arm
Reduces frictional resistance with the camshaft and achieves smooth operation.

・Auto decompression camshaft (standard 10/10D camshaft)
Achieves smooth engine starting without straining the cell motor.

・Optional part: 15/15D camshaft
Improves output performance in the mid-to-high RPM range.

【Super Head 4V+R Combo Kit 181cc】
The combo kit includes the FI TYPE-X (injection controller) for fuel adjustment suitable for the engine parts of the Super Head 4V+R bore up kit 181cc, a large capacity injector, a big throttle body kit, and a spark plug.

【FI CON TYPE-X・Big Throttle Body】
■FI CON TYPE-X
This is an injection controller that can be connected to the genuine ECU with a coupler.
It comes pre-set with various MAPs for each engine specification, so you can simply select the MAP that matches your engine specification and ride.
In addition, you can set ignition timing, accelerator pump, dwell time, invalid injection time, ignition timing temperature correction, engine temperature correction, and vaporization time.
Advanced users can also enjoy setting based on existing MAPs or creating new MAPs.
Since it can be connected to a PC or smartphone even when the engine is running, monitoring of the tachometer, throttle opening graph, and engine temperature is possible.
Ignition mode can be selected from two types: EASY and EXPERT.
It also features rev limit, pit lane limiter, and real-time MAP change functions.

・Big throttle body kit
You can enjoy engine characteristics that maximize the performance of the head and rev smoothly up to high RPMs.
Big throttle body bore diameter: Φ34
Air filter kit included.

■Compatible models
Monkey 125 (JB02-1000001〜)

■Notes
*Since the displacement will be 125cc or more, it is not possible to ride on public roads with a moped license. It is for competition only.
*When installing the bore-up kit, we recommend simultaneously installing a Takegawa special clutch kit to prevent clutch slippage and various mufflers.
*For FI CON TYPE-X installation, a customer's PC or smartphone usage environment and internet connection are required.
*The image is for illustration purposes only. It includes products of different sizes and colors.
*Product designs and specifications may change without notice. Please understand.
