S-stage bore up kit 170cc with FI CON (injection controller).
S-stage bore up kit details The stock cylinder head and stock crankshaft can be used as is, and the cylinder and piston can be changed to 170cc. The S-stage comes with SP Takegawa's original sports camshafts, and when installed with the optional injection controller, the 170cc engine's output is maximized, resulting in a torquey performance that is completely different from the stock engine. Spark plugs included.
FI CON (Injection controller) This is SP Takegawa's original injection controller that can be easily changed by switching the rotary switch on the main unit without the need for complicated PC connection. If you install SP Takegawa engine parts on an injection model, the fuel balance will be out of tune. By installing this controller at the same time, the fuel injection amount is corrected by the 16-bit microcomputer inside the injection controller, which determines the engine condition of the installed vehicle and processes calculations in real time based on the signals output from the stock computer. SP Takegawa's injection controller is capable of injecting more fuel than the stock computer. Built-in 12 types of recommended data for SP Takegawa engine custom specifications and intake/exhaust system combinations SP Takegawa's original dedicated connector is included, allowing installation with minimal wiring modifications.
Points of Attention
* If there may be an instruction manual included, it will be written in Japanese.
Reason for purchase Compared to the same 125cc GROM, it had a slightly inefficient feel.
I felt a lack of torque in the EnduroCourse.
Only the engine displacement volume of the KLX125's car was wanted to be large.
Assembly It is a normal replacement of the piston, cylinder and cam, so please follow the instructions as you go. If you're careful, you should be able to assemble it without any problems.
Check and prepare the necessary items in Manualetc. before assembly. Mo Rib Ten Grease, Screw Locking Agent, etc... If you forget the small stuff Even if you have the Main tool, you won't be able to proceed with the work.
Where and how do you find the gold needle or string that holds the Camshaft Chain in place to prevent it from falling off? I think it's best to think about it so that you don't get in trouble for the actual work.
In the instruction manual, the order of the work and the timeline of the photos used in the item do not match. There was, so it's better to keep in mind the procedure and the condition of the other parts of the system at the time I think it's good
There is an O-Ring that cannot be replaced without removing the cylinder, this is regardless of condition. I think you should have a replacement.
If you follow the instruction manual, you should be able to assemble it without any problems.
I'm afraid of running the engine without the oil turning completely after assembly. Connect the Booster cable to the Battery, pull out the Plug, and turn the Oil. I kept turning the Cell for a while.
Effects (Exhaust System→ FMFPower core4, included #8Standard Plug BP5HA, KLX140Injector, FI CON→D) (High flowPlate, Air cleaner) The torque is more comfortable to ride compared to the 125, even after a break-in.
After break-in, it turns without any problems up to near the let zone. However, the rotation is a little low. The heavy feeling was hard to resolve.
It is a high camshaft, but I don't feel it is hard to ride because it doesn't seem to swing to high rpm than I expected.
Current state (Exhaust System & rarr; SPTakegawa Cone Oval Exhaust System, KLX140 Injector) (#9 Iridium plugs, FI CON→C, High flowPlate, Air cleaner) 0Injector is not an OEM, so the FI CON adjustment value in the instruction manual is not helpful.
This seems to be the best condition for the current situation. The weight of the rotation is gone. It feels like it spins without stress in the whole RPM range.
The exhaust system was changed from FMF to SPTakegawa Cone Oval Exhaust System. The latter is easier to ride because you can feel the torque in the mid to low speed, but High RPMs feel a bit clogged. I think it just seems to get clogged up at higher RPMs because of the increase in low and mid-speed torque. In the case of FMF, it was too loose or didn't have a torquey feel. High RPM for that. The SPTakegawa was spinning comfortably, but in reality, it took a lot of time to reach the maximum speed. It was a good decision to change the exhaust system as well, since it's faster and has a lower medium speed.
Changing the front pipe to an FMFPower bomb or KLX140 OEM front pipe I plan to do so and see what happens. View Detail
I installed it on a 2014 KLX125. It is not a compatible year, but there is no problem at all. I think that it is possible to set the fuel setting of FI Controller rather easily because the symptom comes out plainly though it is combined with the exhaust system which is good for the fatty's exit. However, Mr. Takekawa's concept to be able to play with it by himself. If you look at the Instruction Manual calmly, it is easy to understand with care, but it was really hard to remove the Camshaft holder. This is [Color] If you can clear it, you can use it. It's only 45cc up, but the effect is there. It's just a self-responsibility, but I was able to install it in other models than the fitment year, so please try it!View Detail
