FCR Tuning – Should the Slow Jet Be Changed According to the Season?

Tuning the FCR requires adjustments based on the weight of air and fuel. As the temperature drops, the density of the air increases, making the air heavier. In response, it is necessary to either increase the weight (amount) of the fuel or reduce the amount of air.

FCR Tuning – To What Extent Should Carburetor Synchronization Be Done?

How Far Should Carburetor Synchronization Be Done?When performing synchronization using a vacuum gauge, there are graduations to consider.Is it acceptable for the reading to be off by one graduation?Does even the width of the black line on the gauge count as an error?There are many questions. Recently, I was able to hear the answer from the legend, Mr. Bito.

With the FCR, you can start the engine even on early winter mornings.

I will write about starting the engine of a motorcycle with a carburetor in the early winter mornings. Logically speaking, the Honda Cub, which was commonly used for newspaper delivery in the past, starts the engine easily with the choke and kick start, even on cold winter mornings. Now, regarding motorcycles equipped with FCR carburetors, they don’t have a choke, but you can use the accelerator pump as a substitute. By twisting the throttle about three times and then waiting for about 10 seconds before turning on the starter motor, the engine starts up normally.

Are the standard brakes of classic motorcycles low in performance? I customized my brakes.

Comparison of brakes from the past and present: Even when comparing a CBX1000 equipped with a recently manufactured complete brake system to a CBX1000 that is using well-maintained, 40-year-old brakes, the performance difference is significant.

For FCR Beginners – Don’t use the red Velocity Stack on the street as it is!

When you purchase an FCR, it comes with a red Velocity Stack. It’s a 30mm red plastic Velocity Stack. The Velocity Stack of the FCR can be considered the 'exhaust' on the intake side. It is an essential part for smoothing the airflow.

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.

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.

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.

I went to the 2023 – 11th BITO JB-POWER Meeting.

I attended the 11th JB-POWER Meeting on October 29, 2023 (Sunday). I will focus mainly on the atmosphere of the venue. Photos are compiled at the bottom, separate from the text. My personal reflections will be kept modest, and I will primarily guide you through the venue's ambiance.

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.

Manuals – New post

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.

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.

The recommended installation position for the air-fuel ratio gauge is at the center of the meter.

Where do you all mount your air-fuel ratio gauges? The air-fuel ratio gauge needs to be carefully monitored during high-speed runs, especially on straight stretches of road where it’s crucial to check the readings. On my CBX1000, I’ve removed the stock voltmeter and positioned the air-fuel ratio gauge right in the center of the meter cluster for easy visibility.

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.

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.
