"It was attached to BMW R100RS. The first impression is the feeling which is completely diffrent on another motorcycle. In the carburetor of normal, although it was an impression that accelerator operation reacts after one second, FCR reacts to accelerator operation at a direct, and a thing like the valley of torque does not feel, but it accelerates from the start. Moreover, the speed from an intermmediate speed region reaches to the desired one immediately and it becomes very pleasant. I would like to change setting variously and find the best point from now on. (It is likely to take time a little) It was good to change to FCR."

@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.
