■S Stage Big Bore Kit The S-stage Big Bore Kit allows you to use the stock cylinder head as is, and simply replace the cylinder and piston to make it 125cc. By changing the stock engine from 110cc to 125cc and installing SP Takegawa sports camshaft and FI-CON 2 (injection controller), the output performance is improved and torque-full riding is realized. By installing SP Takegawa's exhaust at the same time, the output performance will be further improved. ■Sports Camshaft (N-15/20) This is the best profile to maximize the performance of the stock cylinder head and improve the output performance.By installing it on the stock engine, the power output in the high RPM range will be improved. ・If you install only sports camshaft with stock piston and stock exhaust, injection controller is not necessary. ■FI Controller 2 (Injection Controller) If you install engine parts such as big bore on an injected vehicle, the fuel balance will be out of tune.SP Takegawa's injection controller is set up to match SP Takegawa's engine parts It has a built-in 3D fuel map, which can be set according to the specifications of the bike.Easy to change settings by switching the rotary switch on the main unit, without any need for a PC is available.In addition, the built-in correction map can be fine-tuned by using the rotary switch on the main unit. A special harness for each model is included, so it can be installed with minimum wiring work. ■The rev limiter cut function is available only when SP Takegawa sports camshaft is installed at the same time. ■The rev limit speed is the same as stock when using the stock camshaft.■Rev limit speed when using SP Takegawa camshaft: 10500rpm ■Big Throttle Body Kit (Stock air cleaner can be used as it is.).) It maximizes the performance of the stock cylinder head and achieves high output.You can enjoy the engine characteristic which turns without stress to the high RPM range.
Points of Attention
* If there may be an instruction manual included, it will be written in Japanese.
I was able to work smoothly with the detailed instruction manual. Cruising has become easier and I can cruise normally without opening the throttle too much due to the lower normal rpm, which results in better fuel economy.View Detail
Initial BigThrottle+FQuantity:I was planning to use only 1pc. of the gun, but I didn't have a good one to attach to JA45 without messing with my bad wiring, and I even did Bore up for the KillUp afterwards. The work was completed somehow while examining it with Net! The point of remorse is that I should have prepared Knock Pin, isn't it? I've only done about 150km on it, but it's easier to ride because the torque has been increased from the bottom and I can now control the traction on corners. It also makes a big difference on hills. After that I added a tachometer to prevent over-revving, but I've only been running it at 7500rpm. I'm looking forward to it! I'm worried about the durability, but I think I can get away with not turning it except for overtaking, so if I don't turn it too much, what do you think?View Detail
