Filtro dell'Aria per Sostituzione

I am using it for 2002 Big Boy. exhaust system is also changed to YOSHIMURA, and it is the vehicle which changed the jet and increased the power, but when I installed this air cleaner, I felt the pickup and the slight torque increase in the whole area more. I am experiencing a slight torque increase. It is the performance up according to the price.

I torqued up the whole area. 04 GRASS TRACKER with Wills WIN's Sharp Exhaust System and NGK's Plug cord with Iridium plugs and Extra Grounding. rarr; I was able to raise it to 130 and adjust the Pilot screw as well. Since it is an impotent motorcycle, I think you can feel the exchange quite well.

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.

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.

[How is it used?
Installed on NINJA2 Helmet 50RR as a replacement for K&NFilter.
Traveling:Touring, mountain passes
Period of use:about 6 years or so
Custom contents:Exhaust SystemFull Exhaust System, air cleaner box drilling, RapidMotorcycleEasy installation.

Was the one you received as per Image?
As you can see in the image, the product looks almost exactly the same as the K&N.

Was the installation difficult?
As with the K&NFilter, I had to insert it with a lot of pressure to get it to go in.
I got the rubber part very wet and then inserted it.

How was your experience with it?
Compared to the K&NFilter, the intake efficiency was slightly lower. I could feel it. But it was really only a slight decrease. Still, the intake efficiency is much better than OEM.
RapidMotorcycleEasy was able to run without difficulty with the same settings as K&NFilter.
The car has been run for about 5000km and the filter has been cleaned and reused. I have not had any problems after cleaning.
Unlike OEM products, this product can be used for a long time with proper maintenance like K&NFilter.
Maintenance restores the performance of the system, so it is important to perform maintenance on a regular basis.
Also, the exhaust system was replaced. (Custom exhaust system) then Quantity:It is recommended that the Air Filter be changed to one with better air intake efficiency in Set.
It's FI, so it won't improve performance as dramatically as carburetor, but it will still make you a little happier if you do it.
The K&NFilter has a Large variable intake efficiency, but is a bit pricey, so I found this product to be more cost effective.

[Included Parts:were they on?
None

[Was there anything that disappointed you?
Difficult to insert.

(Points and hangs of installation, Items to buy together)
Point and hang
You can apply silicon grease or silicon spray to the surface of the rubber of this product so that it can be inserted smoothly. I didn't care about it, so I applied Lithium silicon grease and inserted it. (No particular Trouble has occurred.)

Items to buy together
K&N Filter maintenance kit (FilterCareService kit) If you purchase the product at the same time, you can use it for a long time while maintaining it. (No problems have arisen when used in this product.)

Washing Filter (It can be this product, or another, or you can keep the OEM.)
