FCR if the OEM air cleaner box and carburetor can be removed Installation of the Carburetor Body itself is not difficult
for W400, the load extraction nipple is pre-processed, so it can be used for the secondary Air hose and
the load extraction from the carburetor is done by merging the nipple with the T-joint and then If you connect to Tank's Load Hose
Tank Fuel Switch works

Throttle Cable is an Active Universal 900mm (length limit) I used a 1050 (which was a better choice), but
it does not work with the w400 Switch Box
I had to put the FCR Carburetor Body on the w650 Switch Box beforehand to install the FCR Carburetor Body It was replaced
switch with a screw-tightened throttle, such as the w650 and ESTRELLA I'll have to replace it with a box
I think you'll have trouble with the Throttle Cable

Setting is still in progress, so I can't do a detailed in-play
Acceleration from 5000 rpm becomes quite violent
the sound from the carburetor is also pleasant

At low RPMs, you won't feel the difference from the NORMAL, so it's not as difficult to handle as it usually is
Response is different, but it's hard to feel the power at low rpm
Even if you put in the FCR Carburetor Body, you'll have to turn the W400's Engine after all I feel like I don't have any power
So it turns into a Motorcycle that makes you want to spin it more than necessary

My mileage dropped from 24 to 20 on the high speed, pass Main course

Setting is unexpectedly White
It's one more thing to look forward to in my motorcycle life
If you're interested, I think you should give it a try I don't think you'll regret it

@Brian Yes I had to adjust and tune mine. They come with a base setting from Japan’s elevation and a bit rich to cover themselves

OEMCVK #4Slide valve is worn out and sucks secondary air, so negative pressure is not stable. FCR was the only choice.
Disassembled for inspection of each part and sprayed with Bell Hammer for bearing. Commercialized by Kyoritsu Kougei Co. SEPBearingGuide" The order was placed to install the But I am not sure when it will be delivered. This will protect the Throttle valveBearing from cutting the groove in the Carburetor Body.
I hope it comes soon.

I don't know how well it works myself because I haven't assembled and ridden it yet, but the fact that so many people have used it is the best proof of all.

Setting struggles

The racing cabs are very easy to set up, and once you get the settings right, you will be amazed at the acceleration power you can get. However, setting is very difficult. It is very difficult to set up the engine, because it is mainly used for touring, and it is hard to set up the engine without stress at all openings from the bottom to the top. It is also difficult for amateurs to judge whether the jet is too thick or too thin. Considering the time and risk, I think it is better to leave the setting to the store, but I am impressed when the motorcycle runs after setting by myself.
