FCR

The difficulty of tuning an FCR carburetor varies depending on whether you're using a quick throttle or a standard throttle....

My CBX1000 used to have a very cool BITO machined throttle. I used it for almost 20 years, but I sold it because I changed it to an active Quick throttle. One of the recent themes in tuning the FCR is the feeling of acceleration when opening the throttle suddenly.

The surprising moment when I tried tuning my own FCR - for beginners - Failures 3/3...

In the setting of the CBX1000 FCR, there is one part about what went well, but three parts about what went wrong. It is true that people often learn from their mistakes. So let's get started!

The surprising moment when I tried tuning my own FCR - for beginners - Failures 2/3...

This is the middle part. This blog post is more about setting up the FCR of the CBX1000 than about setting up the FCR. Of course, there may be some parts that are useful for those who are setting up the FCR of the SR.

The surprising moment when I tried tuning my own FCR - for beginners - Failures 1/3...

The other day, I posted about the good things about setting up the FCR of my CBX1000 by myself, but this time I'm writing about the things I failed to do. I was particularly surprised by the things I wouldn't have failed to do if I had asked someone for advice instead of setting up the FCR by myself, and I'll write about the things I failed to do because I didn't know the information beforehand.

The surprising moment when I tuned my FCR by myself - for beginners - Good things...

It's been about two years since I started tuning the CBX1000 FCR in earnest. I'll write about the things that moved me and surprised me while tuning the FCR. I'll write about the good things.

FCR Tuning - Full throttle! Check the main jet for each gear...

This is my method for tuning the main jet of the CBX1000 FCR. Use a chassis dynamometer. This is written in a slightly abstract way, not in a precise way.

FCR setting - Installing an air-fuel ratio meter makes setting easier....

I have a PLX-DM-6 on my CBX1000. I see a lot of different expressions on the internet for carburetor settings, such as rich, lean, bumpy, and overhanging, rather than FCR settings. These are just the expressions used by the writers, so I'm not sure if they apply to the settings of my motorcycle.

FCR Tuning - Look at the air-fuel ratio during acceleration, not partial...

Looking back on this year, there are some things I pay attention to when setting up the CBX1000 FCR that I didn't do in 2021. I try not to look at the air-fuel ratio when in partial. Partial means a stable riding state with the throttle fixed. The following post is written under the assumption that an air-fuel ratio meter is installed.

FCR Tuning - Where should I tune the main jet at full throttle?...

This is about the main jet settings for the CBX1000. You may not need to worry about this too much on a small motorcycle, but where should you set the main jet on a large motorcycle? There is only one answer. [Chassis dynamo] Nowhere else to do it other than on the chassis dynamo. You can sign a contract for about 200,000 yen per month.

Selecting a jet needle for the CBX1000 FCR model - I want to choose something other than the 90FXM...

The current CBX1000 FCR jet needle shipped by BITO is apparently 90FXM#3. I called to ask. The 90FXM has a special cut-out with an [X]. Normally it's [T]. I don't want to change the taper angle, but I'd like to change the straight diameter in various ways, but there are no options.
