Setting completed
Racing carburetor is still fun!
Run several times in the actual run setting.
Jet needle step change is almost ok.

Very suitable for my bike
I owned an SR400 and the carb fit so tightly inside the frame so I cannot adjust the idle screw. Thankfully I've found this product for my carb and even my bike. View detail
It performed exactly as I expected. (*^^*)
Quantity, depending on the individual:Pair (for Left and Right) I think it will be done, but I was able to turn comfortably by adjusting only the Needle clip. View detail
This is required for Power Filtering.
This O-Ring is required when converting a small body FCR Carburetor Bodycarburetor into a Power Filter.
Used between Power filter adapter and Carburetor body.
This is essential to prevent secondary air.

Due to Normal cab malfunction
Purchased due to Normal cab malfunction
Difficult to adjust from Idling to high rpm 。。。。 Low to medium speeds are especially difficult

The FCR Carburetor Body you've always wanted!
I had been on the fence about buying it, but I was informed that the price will go up by about 32,000 yen starting April 1.
I made the decision to purchase.
The setting for the car model was already out to some extent, but once the Jet and other products were installed, it was not possible to use them.
Checked the number of screw-related returns and tuned the throttle valve.
Also, I installed a SEPBearingGuide (I'll skip this since it has nothing to do with product impressions).
Installation is easy for those familiar with the OEMcarburetor, as it simply replaces the OEMcarburetor.
After starting the engine and adjusting the idling, the car was ready for a test run.
As expected, FCR Carburetor Body Response like a demon!
Acceleration like a demon...?
The Exhaust System has been replaced with an external one, so it is obviously thin. (Breathing at 6000 rpm)
Quantity of Main jet in the future:Set is purchased and Setting is issued.
Low speeds run without any problems.
After all, it is shipped with the settings for the car model, so it will run to some extent.
From there, I'll boil it down to my own taste.

Recommendation to Touring groups with FCR Carburetor Bodycarburetor!
With an external carburetor, Funnel and Power Filter would be effective to get the best performance.
I was worried that the mixture would become thicker in rainy weather due to humidity, and I thought it would be safer to seal it with a normal filter.
good point
The FCR Carburetor Body can be used with the Normal filter intact.
Adapter's accuracy is solid, so there is no need to worry about secondary air.
No need to worry about running in the rain.
Carburetor setting is not severer than with the Power Filter.
A bad point
The price is high.
Compared to the Power Filter, the ride is mild at best, and insufficient at worst.
Installation is difficult without removing the Seat.
I think the choice is between performance and durability.
After all, the carburetor does not have to be external, and the OEM could have remained the same....
It is hard to feel, but FCR Carburetor Body has better high-rpm extension and Response than OEM.

FCR Carburetor Body of your dreams
My first impression of the installation was that the Throttle was very heavy! No amount of Wire routing or type of Wire could improve it.
So we changed the Spring to a lighter one, and it now feels as good as the OEM one. The spring change is not possible without a full reverse operation.
Other than that, the acceleration power is as good as its reputation.

Good quality
The installation itself is very easy. However, it takes a little getting used to the settings. However, the manual comes with the product, so you don't have to worry. View detail
It's a reImpression I used for 3 years.
I did an impression once right after I bought it, but there were a lot of errors due to lack of knowledge, and the setting had not been published, so here is my impression again after 3 years of use.
The OEMAir Cleaner Box was used for installation, and OEMWire was used for the Throttle Wire.
An adapter for Active's Power Filter is used for connection to the OEMAir Cleaner Box because its diameter is the same as that of the Air cleanerbox.
So, other than the FCR Carburetor Bodycarburetor, as long as you have the Adapter for Active's Power Filter, you can install it on the W400.
At first I used Power FilterSpec. but I was not satisfied with the performance even though I did my best in Setting.
I think the OEMAir Cleaner BoxSpec. is the only choice for W400!
Driving performance is improved from the moment the throttle is opened.
Even in the normal rpm range of around 3000-4000 rpm, the power is clearly different from that of the OEM.
Especially when the Axel is opened, it gives a direct feeling, so just by subtly turning the Axel on and off, you can make your motorcycle more enjoyable.
However, the sense of pulse when idling is reduced, and it becomes a rotating type of engine instead of a thumping type of engine.
The Engine vibration itself increases when turning.
The Shipping Settings were honestly a mess!
The Slow Jet that came with the shipment had a 38 on it, but it was too thin to idling properly.
Jet needle is FTM, but it is also useless, I don't think FT system is right for it.
In the end, Slow Jet settled around 45 and Jet needle around EZQ!
Main jet remains at 125 and Large body can be used except in winter, so you need to prepare Throw and Needle first.
Setting also affects the exhaust system, so this is not the correct answer, but it is best not to rely on the factory settings.
By the way, the Exhaust System is Wyvern classic.
Fuel consumption depends on setting
When riding around town, use the thicker Emphasis on Torque setting to achieve around 21km/h. When touring, use the thinner Emphasis on Torque setting to achieve around 27-30km/h.
You will be able to set it to your liking, so we are not talking about going up or down compared to the OEM.
The condition of the Engine changes every day due to the different temperatures and the different fuel tone.
It is not always 80 because we don't set up every time, some days it is 70, some days 95.
Spring, Fall, Summer, and Winter Setting for a minimum of Season is required
You'll be constantly feeling the Engine's burn, and that's more fun than you might think!
W400 is less difficult to set up because you can replace the jets without removing the carburetor.
If you like tinkering with Motorcycle, you will enjoy it including Setting!
I will recommend it.

FCR Carburetor Body37Black body
The product was originally scheduled to be shipped in February, but was accelerated and the product arrived in November.
It runs with no particular problems after being popped in.
It looks cool and I am very satisfied.

Great product!
OEMCarburetor was not doing well, so we took the plunge.
High turnover in spite of being pontoon-mounted without setting
Acceleration and extension in the rolling range were of a different dimension.

Very easy to handle racing cab
The standard VITO FCR may have the engine displacement volume, camshaft, exhaust system, etc. in the NORMAL condition. If so, we can assume that the people who choose this FCR are those who have changed the Engine Displacement Volume, Camshaft, Exhaust System, etc., so there is no way that the standard condition is good.
persistently Engine will take." The FCRManual is in about the same state as the FCR. Therefore, if you read the attached FCRManual carefully and do not assemble the product immediately after it arrives, you will surely fail. Be sure to read the manual carefully. This is the shortcut to success.
Remembering the smell, sound, and color of the exhaust in the current Carburetor, even if it is just a good sense, will be helpful in setting up the FCR.
And Is it thin?" When we consider the situation and take measures to solve it, it gets worse and worse, and we often find that it is very thick. Therefore, I think it is a Large thing to shake the number of Jet, etc. to the opposite direction when things go wrong, instead of doing it with a fixed mind.
It is also important to know in which season the Setting was issued. When the season is on the opposite side of the Setting, it will be easier to run if the fuel is changed.
I think it's very nice and easy to prepare for the first time.

OEM-like structure
The standard FCR Carburetor Body is left hanging in the middle. Therefore, it is impossible to turn this screw while the driver is riding. Some people have used a tie wrap or other device to put it on the left side of the body, but this is the same structure as the OEM carburetor, where the bracket is attached to the #1 bolt that holds the float chamber in place.
It's easy to use things, so it's very useful.

Should have bought sooner.
Tuning takes time, money, and patience.
Already experienced with OEMcarburetor…
Therefore, I left it to PRO.
It was worth it.
It is different with the suction sound.
I am impressed by more than the Gold amount.
If you are in doubt, you should buy soon.
Uotani and Quantity:Set is recommended!

Last Racing cab
And you won't find a better carburetor any more.
The number of available vehicles will gradually decrease.
Pleasant blow off and easy to tweak by yourself.
Taste the face White while you still can.
