The throttle opening and throttle valve opening of the FCR carburetor are not directly proportional.

Even when the throttle is opened to 1/2 on an FCR, the throttle valve on the FCR does not open to 1/2. This is not specifically mentioned in the FCR tuning manual. Knowing this might change your perspective on the operation of the FCR throttle. At 1/2 throttle opening, the throttle valve is typically open only about 1/4.

With the quick turn throttle housing, you can set the throttle free play to 0mm!

When installing a quick turn throttle, one feature that is not present in a standard throttle housing is the throttle stop screw function. Although it might sound elaborate, it is simply a screw hole that has been cut. It is a bolt used to adjust the minimum return position of the throttle.

Throttle grip wiring – The FCR is a push-pull carburetor. Its direct operational feel is very appealing.

For adjusting the throttle area, there's no problem at all in thinking that you can easily do it yourself without needing to rely on a professional. For such tasks, you can usually find methods by searching online. If you still have trouble, you can consult a local motorcycle enthusiast, and you’ll likely find a solution.

FCR Tuning – Testing 6 Variations of Accelerator Pump Diaphragm – 2023-08-22

One of the highlights of FCR carburetors is the accelerator pump. This time, instead of making just minor adjustments, I performed tuning with all the diaphragms I have on the same day. The accelerator pump diaphragms tested were Standard, KLX250, and KLX400, with discharge timings of 1.0mm and 0.5mm, resulting in a total of 6 different patterns.

Adjustment of Motorcycle Throttle Free Play

Throttle Free Play Basics. The standard throttle free play is typically set to 5mm. Additionally, it’s essential to ensure that the throttle returns properly when the handlebars are turned left and right. This ensures that the throttle operates correctly and safely.

UperCowl – New post

Installing the cowl on CBX1000 is not difficult.

I received a question about installing a cowl on the CBX1000,so I will write about it in a column-like manner. Bikini cowls can be easily installed on almost any naked bike. Let's move on with the subject being a frame-mounted cowl.

2023.03.092024.05.02

I love CBX1000’s painted accessories.

This story uses photos taken at a rental garage. My CBX1000 has a repainted exterior. We also store the normal exterior separately.

Riding is fun when you attach a cowl to a naked motorcycle

Driving review with CBX400F Integra cowl installed on CBX1000. I am not talking about how easy it is to drive without the wind,or how it looks,but it is a lot of fun to throw it around and knock it over. My riding technique is rather poor. And if anything,it feels like a straight line number.

FCR carburetor tuning – test run on the expressway and Kizuna Stadium in Iwakuni

I have been told that a Saturday Night meeting will be held at Kizuna Stadium in Iwakuni from 19:00 on October 22,2022. Along the way,I also tried driving the FCR while checking various air-fuel ratio gauges and paying close attention to the effectiveness of the accelerator pump.

FCR – Test run on the expressway – Check the condition of the main jet

The speed is within the legal speed limit. Fully open the throttle while looking at the gears like 3rd,4th,and 5th. CBX1000 is a motorcycle with up to 5 speeds. 3rd and 4th gears provide peaky acceleration. When you shift to 5th gear,it won't accelerate comfortably until you get up to a certain speed,but it feels like it will gradually increase the top speed and accelerate.

FCR tuning – AS air screw adjustment – 2022-08-03

I wanted to eat curry for lunch,so I went for a light FCR test run. With my ability,I can't decide on a good screw position in one go,so I just do test runs and try different screw positions from rich to lean.

I found a box for a CBX1000 FCR from over 20 years ago in the back of my room.

This is the box that my CBX1000 FCR came in. It's not uncommon to find parts from decades ago. It's a little unusual to find just the box. The contents are still in good working order. Judging from the packaging of the box, is it the same as the CRS carburetor? The illustration shows the CRS carburetor, not the FCR.

Buying a CBX1000 FCR – How to tune for the first time

Many people want to install a racing carburetor on the CBX1000. In Japan,the options are the BITO FCR or CRS carburetor. It seems that TMR can also be made to order,but it is not common. If I were to buy one,I would choose the FCR.

Motorcycle Intake Systems – Which is Better, Fuel Injection or Carburetor? What are the Differences?

I write about FCR carburetors all year round, but this time I will cover the differences between fuel injection and carburetors. While I can’t go into great detail, I’ll provide a rough overview. For those unfamiliar, this might serve as a small topic for tomorrow’s ride. To get straight to the point: fuel injection is simply outstanding.

FCR tuning – Acceleration pump adjustment – If it is too fast, it will hit the throttle valve.

Write down what will hit you first. I found a case the other day,where the fuel injection from the FCR's accelerator pump hit the throttle valve. The fuel is not being sucked into the engine,but is instead hitting a door called the throttle valve.

My CBX1000’s Photo Gallery

This is my CBX1000 photo gallery.
The cowl is attached to the CBX400F Integra upper cowl using the [CBX] SC06 stay.
It can be changed to a naked specification instead of a cowl installation that cannot be reversed.
The matte black exterior has been changed to glossy black, including the meter, turn signal side cover, and rear fender. Added lines to the front fender.
