Cost and Performance

Power Filter, the standard Tune for intake and exhaust, Powerful.
The Power Filter makes the air flow smoother and provides air without stress to the throttle work, making the engine more responsive and increasing torque and power.
Throttle response when opening the axel has also been improved, and you will be surprised at the difference in the comfortable start.

Setting the carburetor and injector is essential for installation. After the carburetor and injector are installed, the power of the carburetor and injector can be experienced, but there are also Merit and Demerit.

Merit to be replaced by Power Filter
[Merit1] Power up The shorter the intake pipe is and the rougher the filter is, the more air resistance can be reduced by replacing it with an air cleaner. 。 Most OEM filters that use filter paper, etc., have low airflow per area and large intake resistance, whereas the mesh Power Filter has much lower intake resistance. 。 When the intake resistance is reduced, the negative pressure resistance when the piston is lowered during the engine intake process is also reduced, so both power and response can be increased. 。 The higher the RPM, the more air intake per hour, the larger the benefit will be, and as long as the fuel condition is well controlled, the power can be increased by replacing the power filter. 。

[Merit2 Sound change The Merit of replacing with the Power Filter is that the intake sound becomes easier to hear. 。 Normal air cleaner box is designed to reduce intake noise, so intake noise is barely audible 。 The bare power filter directly emits the sound of the engine intake, and this alone creates a sporty atmosphere. 。

[Merit3 Space-saving By eliminating the air cleaner box, which occupies a large volume of space in the motorcycle, the available space can be effectively utilized. In addition, it contributes to weight reduction. 。 Mopeds with less loading Space can increase their loading capacity, albeit slightly, by installing an Accessory Case! 。

It seems to be a Power Filter full of good things, but there is also this Demerit.

Power Filter Demerit

[Demerit1] When replacing the noisy Power Filter, not only the intake sound but also the blasting sound of the Engine and even the Mechanical Noise can be heard.
The air cleaner also serves as a silencer, and replacing it with a power filter will significantly reduce the silencing performance of the intake system, etc., so when the RPM is increased, the noise may be greater than the exhaust noise. 。 I like it (laughs).

[Demerit2] Low-speed Torque becomes thinner and harder to ride. 。 The Power Filter and direct carburetor certainly increase power by reducing intake resistance, but precisely this is only the result of the TorqueBand shifting to a higher RPM side. Therefore, the starting acceleration may seem weak, or the TorqueBand may lack the feeling of Torque when the Throttle is slightly opened, and the motorcycle may become difficult to handle.

[Demerit3] If the Power Filter has a nipple to install the blowby hose, there is no problem if the hose can be inserted there. However, it is illegal to release the blowby gas discharged from the engine to the large airflow because there is no installation point for a blowby hose. 。 Blowby gas is sucked out by the negative pressure of the intake air and is discharged because the replacement of the Power Filter or opening of the large air intake does not provide enough negative pressure as the OEMAir cleaner box does, and blowby gas cannot be sucked out as efficiently, The increase in the internal pressure of the engine crankcase prevents the piston from moving, resulting in power loss. 。 While replacing with a power filter will increase power by reducing intake resistance, it may also cause power loss by reducing blowby gas discharge efficiency.

Based on Merit and Demerit, I purchased KIJIMA's Power Filter this time, and it is not bad relatively speaking. In a word... it runs well (with Carburetor setting).

good point
◎Filter capacity, well treated joints, and durable performance.

◎Cheaper than K&N.

After Fire will not appear.

A bad point
◎ Cannot be used on rainy days. →Because it absorbs water.

◎Intake noise became annoying.

◎Carburetor setting is required.

◎Engine characteristics become closer to high rpm. →If I say that it has come to revolve, it does (laughs).

◎Cleaning will be necessary for the blisters.

Some people do not have the Merit to install the Power Filter from Demerit, but it depends on how you use it and the form you want to use it in.
The purpose is to set the intake and exhaust to match the current running conditions. 。 In such cases, we think the Power Filter is a logical part. View detail

Asymmetric shape is good

[How is it used?
NSR250R (MC21) I was looking for an air cleaner that matches the size of the TA22Carburetor (54mm).
The OEM air cleaner box was originally missing, so I would have preferred the OEM one, but I chose this one because used parts are very expensive and I basically don't ride in the rain.

Was the one you received as per Image?
It was just like the picture.

Was the installation difficult?
The TA22carburetor is so close between cylinders that a regular cylindrical one would interfere.
This product could be installed thanks to its Oval and One Side joint.
Installation is instantaneous as all you have to do is tighten the band.
I was a little concerned about the loose insertion before tightening the band, but once the band is tightened, it is firmly secured.

How was your experience with it?
NSR250R for Package (up to 89) but MC21 (90) But there was no problem.
It is a mystery why Carburetor is almost the same, but it is compatible up to 89. Is it because the shape of the air cleaner box changes and it is not confirmed yet? I think it is because the shape of the air cleaner box changes and has not been confirmed.
There was no particular interference with the Fuel Tank or Others components.
It is universal, but as stated in the Package, it seems to fit NSR250R/NS250/CB750F/CB900F/GSX1100S.

[Included Parts:were they on?
The tightening Bandetc. is also included in the package.
As long as you have a Driver, you can install it.

[Was there anything that disappointed you?
Not particularly

【Review】
The asymmetric shape is good for TA22.
It is difficult to say what the compatibility information is, but I am satisfied because it is cheaper than buying a used air cleaner box and filter. View detail

Difference between K507-602 and 604

48mm is already a Quantity:I've bought about 5pcs. and have no complaints at all, so I have high expectations for this one too.
With Mukawa and Minimoto, the Crack cracked and ended up not lasting a month, but with KIJIMA, several years are assured.
The most important thing to remember when assembling the Bolt is not to overtighten the Bolt.
The 48mm 1pc. was over-tightened, distorting and ruining the reinforcement plate inside.

By the way, besides this K507-602, there is another one called 604, but no one has mentioned what exactly is the difference.
The difference is the shape and position of the mountain that fits into the anti-dislodgement groove on the carburetor side.
This 602 is made to fit KEIHIN grooves as it says it is PE28 compatible.
When viewed from the carburetor slot, the mountain is slightly triangular in shape and deeply attached.
PWK28 is the same, and a small CR or FCR carburetor body can also be attached if it fits.
And 604, but it is VM/TV26 compatible and the mountain is round and attached in a shallow position.
TMR28 also seems to fit.
I see that the Rib dimension in Mikuni's Spigot ring dimension chart is different between KEIHIN and Mikuni.
There is such a difference, so make sure you buy the right one.
Especially note the carburetor that can be replaced by a Spigot.
Well, I think KIJIMA is a bit unkind… The dimension chart looks the same for both with a 35mm mounting diameter.
AlreadyQuantity:1pc. if you have a picture.
By the way, Hi-Chi Trading had a picture.
Good luck with WeBig. View detail

KIJIMA KIJIMA Air cleaner

Used for NSR50.
Installation is not difficult and easy.
The air cleaner is considerably smaller than the OEM air cleaner, making it easier to maintain. View detail
