Standards: Monkey(FI) Package Size: 155 x 765 x 330 (mm) Included: FI-CON PLUS / Big Throttle Body Kit [Set components] R stage cylinder head (combustion chamber shape), forged aluminum pistons, all aluminum ceramic mesh cylinder, increased stroke crankshaft, etc
*Stock exhaust can not be used.Please use the Bomber exhaust made by SP Takegawa.(Stock exhaust cannot be installed even if SP Takegawa clutch cover is installed at the same time.) *Use SP Takegawa Crankshaft Support Plate to reduce the load on the crankshaft.The crankshaft support plate has a built-in bearing and supports the crankshaft journal.The crankshaft support is changed from the stock 2 points to 3 points, and the crankshaft runout at high rpm of the big bore engine can be restricted. *Please do not install the H.I.D. kit of SP Takegawa at the same time because it produces high voltage noise which affects the digital circuit.Failure to do so may result in malfunction or failure of operation. *Please do not install the ignition system of the outside product of SP Takegawa at the same time because it becomes a cause of the malfunction and the product failure by the increase of the radiation noise accompanying the ignition voltage increase. *FI-CON PLUS is only compatible with the combination of SP Takegawa parts.If you combine parts made by other companies, the setting will not appear. *Depending on the lot, the product may be delivered with the old price and label with the old JAN code before the price change.
The long-awaited R-Stage 106cc combo kit with stroked-up crankshaft for the Monkey (FI) is available!
■R Stage Bore & Stroke Up Kit By developing a crankshaft with an increased stroke specifically for the Monkey (FI), a large increase in displacement has been made possible.Combination with R-stage cylinder head The engine is equipped with a special FI-CON PLUS (Fuel Injection Controller) that optimizes fuel injection and delivers high output that cannot be compared to a stock engine. Furthermore, by installing the big throttle body developed for the R stage cylinder head, you can enjoy the original performance of the R stage engine to the maximum. ■R stage cylinder head This is SP Takegawa's original cylinder head that was developed by constructing the optimum valve pinching angle, combustion chamber shape, and port shape in conjunction with the use of large diameter valves. IN / EX port: The port diameter of the stock cylinder head is 20mm for both IN and EX, while the port diameter of the R stage head is 20mm for IN: 24mm / EX: The diameter has been enlarged to 20mm.In addition, the 3-dimensional port shape, combined with the enlarged valve port, allows more intake and exhaust gases to flow smoothly. IN / EX valve: Stock valve diameter is IN: 20mm / EX: The valve diameter of the R-stage is 16mm, while that of the IN: 26mm / EX: Larger diameter of 22.5mm. The weight increase due to the larger diameter of the valve is kept to a minimum by waist machining.(Valve stem shaft dia: 4.5mm) Camshaft for R-stage: The camshafts are specially designed to fit the R stage cylinder head. Valve Springs: Unequal pitch (2-step pitch) single valve springs are used to prevent surging at high RPM. ■Piston: Forged aluminum pistons are used (compression ratio 12.0: 1) ■Cylinder: All aluminum ceramic plated cylinders.It is a cylinder with excellent durability, airtightness, and heat radiation. The cylinder is equipped with a boss for oil extraction, and SP Takegawa's oil cooler kit can be installed.If the oil cooler is not installed, use the supplied oil plug bolt.Since the M5 temperature sensor can be installed on the oil plug bolt, the cylinder temperature can be measured by using SP Takegawa's compact LCD thermometer. ■Stroked-up crankshaft (50mm stroke): The weight of the loudspeaker is reduced by cutting the balance of the loudspeaker in order to reduce vibration and improve pickup. Special bearings are used in the journal area where the stress of the crankshaft is concentrated, and the shaft diameter has been increased from the stock 20mm to 22mm for increased strength.
■FI CON PLUS (Injection Controller) (R-stage 106cc compatible/big throttle body compatible) This is the FI Controller PLUS with a new built-in map for the R stage 106cc.It has a 3-dimensional fuel map and can perform high-speed calculation based on signals from various sensors to optimize fuel injection according to engine conditions.In addition, not only the fuel injection circuit but also the ignition system circuit is built in, and the ignition timing is optimized according to the R stage.With these modifications, the ECU can be used up to higher rpm than the rev limit of the stock ECU. *Please adhere to the specified operating speed. While FI CON PLUS boasts such high performance, fuel correction from the basic map (-10% to +20% in 16 steps) and limiter speed setting (7000 rpm to 16000 rpm in 16 steps) can be easily set by simply turning the rotary switch on the FI CON PLUS main unit with a screwdriver. The rotary switch on the FI CON PLUS can be easily set by simply turning the switch with a screwdriver.No complicated PC connection is required.
■Big Throttle Body Kit This is a big throttle body developed for SP Takegawa's R stage cylinder head.This kit is included with the R stage 106cc combo kit. The intake manifold is designed to fit the R stage cylinder head to increase the intake efficiency and the large capacity injectors increase the fuel injection volume to maximize the performance of the R stage.
Points of Attention
* If there may be an instruction manual included, it will be written in Japanese.
As 106 cc Kit came out where I felt the limit to 50 cc, I jumped (Lol) In order to form this kit from NORMAL vehicles, Crank Support plate and Reinforced Oil Pump are necessary. Assembling had trouble installing Piston Pin's Circlip. I missed one by a promise. There was no interruption of work as I had stocked Mukawa's Circlip at the neighborhood shop.. I just started the engine but Compression is high and KICK needs attention. The startability was better for FI Controller with increasing Dial 1 to 2. Immediately after break-in and Setting, I Impression Impression.View Detail
