Perfect replacement

This air filter is made in Taiwan. After replacing the original air filter, the bike feels smoother to move. No more jerking, it moves smoothly.Hope it can last as long as the K&N model.Thank you.

It is replacement from the air cleaner of NORMAL. exhaust system was replaced in order to raise the minute intake efficiency which goes up because it made Other Brand Product. Since it can be used for a long time with regular maintenance, I think that it is economical.

Since durability and Kos Puffo are just exchanged, three stars.

I set the fire condition with Full Exhaust System + OEMAir cleaner, but when it changed to Air cleaner here and set it again, it became powerful enough for anyone to experience it.

Since durability and Kos Puffo are just exchanged,...

Bubbles in Packing area

There are bubbles in the packing part. You can not get in close contact with you?
If this is the case, it seems to be useless to enter Garbage in the Engine.
Bubbles are full of bubbles and nothing to talk about.

Since the air/fuel ratio has dropped, perhaps it means that the amount of air being sucked in is decreasing?

About volume
I changed from OEMAir cleaner to this Cleaner and
The first surprise was that the volume of the exhaust sound became LARGER.
I am satisfied with the sound as it is not as loud as a bomb.
Since the air-fuel ratio has become denser, perhaps more fuel is used and the explosion sound has become LARGER?

Fuel Economy
It has dropped, from refueling immediately after replacement to the present time.
It is 2 km per liter less than before the replacement, so I am sure it will go down.
I am a little dissatisfied with the fuel economy I want.
I am disappointed that the opposite was true, as I thought that purchasing this product and increasing air intake would increase fuel economy.
But the fuel economy just dropped to 30→28, so even at 5,000 km, there's only one refueling difference.
Maybe there's no point in worrying about it.
I wonder if it takes longer to turn until acceleration because the air/fuel ratio has been thickened and the low-speed Torque has been lowered.
I don't know if I am using too much low rpm or more fuel injection.

About air-fuel ratio
It's down about 2 from the OEM, so was the OEM simply breathing more air? I guess that means.
Since the power is higher than OEM from 5000 rpm onward, does this mean that it is now a high-revving type?
I've never been to Circuit, and the OEM had a slower Torque for me.
OEM may be a better fit.

Conclusion
Isn't this product to lower the air-fuel ratio and make it a high-revving type to increase the maximum output from mid-range RPM?
It is not a product that sucks in more air than the OEM to increase the air/fuel ratio and improve fuel economy.
Well, if it is turned up to 5000 rpm or later, the acceleration is increased, so it may be better if it is turned.
I don't know what the fuel economy will be.
However, the last time I refueled, it was over 30, so if I change the way I drive, can I still maintain fuel efficiency? I am not sure.
