● Mounting parts: Air filter replacement, intake suction kit

The response of the normal + air filter replacement was really compatible, and the response was so good that the sports mode became unnecessary.
Based on this, I installed the intake suction kit this time and expected the synergistic effect further, but it was a disappointing result.
I feel that the response in the low rev range of 1000 to 2000 has deteriorated since I started running and started to open the accelerator that I usually use for city riding.
Even so, it's a pity that the sure response obtained by replacing the air filter became dull.
At low revs, the response had to be increased unless the accelerator opening was also large, so sports mode became necessary.
I feel like I have to step on the accelerator more, and the fuel economy seems to be worse, so I wanted to remove it and return it to normal.
In the mid-range rotation of 3000 to 4000, I feel that the torque feeling has increased a little, but the accelerator is open as it is.
For some reason, if I didn't step on it, the rotation wouldn't go up.
The more you step on the accelerator, the more effective it feels, but the more automatic the dullness remains, the more delicious it becomes.
