Air Filter

5/5

I feel like we're getting more and more OEM90-ized (laughs).

I had Powerful on, but the intake sound was LARGE, and I was worried about driving in the rain.
The goal is to make maintenance easier, improve year-round performance, and increase intake efficiency.

What is Motorcycle's Air cleaner?
It catches dust and dirt in the air that is sucked into the engine and delivers clean air that is free of fine garbage to the engine.
(?name? (air cleaner) Airborne dust (Jin'ai) A device that removes In other words, an air purifier.

The need for air cleaners.
… The most important role of Air cleaner is to remove Garbage from the air that the Engine sucks in, so that the Engine will not be damaged. 。 There are various kinds of Garbage in the air, and when your motorcycle runs, it also raises Garbage on the road surface! 。 If such Garbage gets into the Engine, it will damage the internals.

Type of Air cleaner
■ Dry." … Dry type air cleaner is one in which the Element is dry (Type not soaked in Oil, etc.) and is more likely to pass fine Garbage than wet type, but is less expensive! 。 Garbage on the surface can be blown off with an air gun, but the dry type cannot be washed when it becomes dirty, so replacement is fundamental.
*CUB is this Type.

Wet." Wet type is a type of Urethane sponge soaked with oil, and has a characteristic of adsorbing Dust more easily than dry type. 。 Many wet elements can be cleaned and reused by washing them with kerosene, drying them, and soaking them in a little special Oil or 2Cycle Oil. 。 Wet type is slightly more expensive than dry type, but it is more economical if used for a longer period of time because it can be used while cleaning.
*SR400 is this Type.

Screwcass formula." The…Screwduster type filter is a method in which oil is soaked into filter paper and dust is adsorbed onto the oil. 。 They have low ventilation resistance, filter moisture, and are either disposable or washable and reusable. Many are non-reusable and must be replaced.

[Neglecting air cleaner …]
Combustion efficiency is reduced.
Failure to replace the air cleaner will reduce the amount of air that is drawn in, resulting in a change in the air/fuel ratio (mixture of gasoline and air) and adversely affecting combustion efficiency. 。 Poor combustion efficiency can easily lead to abnormal combustion and unburned fuel, which can cause Knocking and other problems.

Fuel consumption will decrease.
The decrease in combustion efficiency will cause the engine to run out of steam, which in turn causes the Axel to open more and more, adversely affecting fuel economy. 。 The need to open the Axel more to achieve the same speed as before has a negative impact on fuel, especially when driving up hills and at high speeds. 。

The Engines are not hanging on well.
The Engine will not be able to get the amount of air it needs, so it will be harder for the Engine to hang. 。 The engine runs slower, which increases the time required for the cell to run, which in turn increases the load on the battery, which can be especially slow in winter and on days with low temperatures. 。
▲Engine suddenly stops.
Failure to replace the air cleaner may cause the engine to suddenly stop when idling or at a stoplight. 。 At low RPM and Idol conditions, compared to when running, the Engine is more likely to stop, partly because the amount of air supplied is lower to begin with.

Additional notes
Ideally, air cleaner should be cleaned or replaced after 5000 km.

good point
◎Use OEM type air cleaner→.
Air intake noise is quieter with Cleaner in the Air Cleaner Box.

The intake area is also larger than that of the ◎50 OEM, so intake efficiency is definitely improved.

◎Fuel consumption is not bad.
◎Filter in the box, so it can be run in the rain.

A bad point
The 50OEM Air Cleaner BOX will not fit the 90OEM Type Air Cleaner, so you will need to purchase a separate box for the 90. Also purchase a CONNECTOTube (a pipe that connects the carburetor and the BOX).

What is the difference between Power Filter and Air cleaner? Power Filter generally refers to the product name, but non-OEM air cleaners are sometimes referred to as Power Filter, while OEM products are sometimes distinguished as air cleaners. 。
Power Filter→ Some products claim to increase intake air efficiency, but increased intake air efficiency can prevent blowby gas from being discharged from the engine, which can interfere with the engine's combustion efficiency. 。 It is safe to replace it with an OEM air cleaner element (filter) unless the air cleaner box cannot be installed due to customization.
The OEM is also more durable and the Filter itself is less expensive than the external Powerful, making it more cost-effective.
Even a single filter can improve engine startup and fuel economy! 。

I've been playing around with it a lot, and I have to say, every time I switch back to OEM, I realize how good OEM is (laughs). View detail
