This is a list of articles about my FCR carburetor tuning. I go to work many times. I am using a 6-unit vacuum gauge.

FCR Tuning - Re-synchronization after adjusting the throttle cable - 2023-08-01...
I synchronize the FCR carburetors on my CBX1000 more than 10 times a year. Whether 10 times is a lot or not, I’m not sure. It’s not that I feel the synchronization has drifted while riding and then correct it. Rather, it’s because minor misalignments occur when I perform tuning and have to remove and reattach parts.

Carburetor synchronization is not the kind of maintenance where you can fail – the challenging part is the preparation....
Carburetor synchronization is a task that can be considered simple. The challenging part is that the preparation before the task can be a high hurdle for beginners. Once the preparation is complete, most people are able to successfully perform the synchronization on their own.

I want to synchronize the FCR carburetor myself after installing it....
Whether it's a CBX1000's six-cylinder or any multi-cylinder carbureted motorcycle, if you own one, you'll likely want to handle the synchronization yourself. Standard vacuum-type carburetors are not frequently tuned, so many people leave this task to professionals.

FCR Tuning - Will tuning improve the return to idle?...
There is one thing I pay attention to when tuning the FCR of the CBX1000. That is, I frequently adjust the synchronization of the carburetor. This time, I will write about the return to idle of the FCR when idling, including synchronization. In the first place, everything I write may be a placebo effect. However, there may be some points that are correct. Please read it with that in mind.

FCR Tuning - What is the air-fuel ratio at idle?...
As the title suggests, this is about the air-fuel ratio of the FCR when idling. The air-fuel ratio of my CBX1000 when idling is around 13.5 when the engine is cold, and around 12.9 when the engine is warm. This is just based on my current preference. A senior Z enthusiast told me that the air-cooled Z series is 14.

FCR Tuning - Synchronizing six FCRs is the best part of tuning...
Carburetor synchronization is the best part of tuning an FCR. It's one of the things you want to learn the moment you realize you want to be able to tune. This blog post is not going to be mainly about how to synchronize a CBX1000. It's going to be a column about the importance of synchronization.

FCR tuning - Carburetor synchronization work - 2022-11-02...
I had time,so I did some synchronization work on the CBX1000's FCR carburetor. If you play around with the idling stop screw,you will notice a difference between the carburetors in groups 1,2,and 3 and the carburetors in groups 4,5,and 6,which is a concern. Recently,I have been focusing on tuning the throttle to a low opening.

FCR Tuning - Adjust and synchronize air screw and pilot screw - 2022-10-27...
I tightened the pilot screw from fully open. I feel that there is no problem with rich when the throttle opening is slightly opened from fully closed,but too rich is not a pleasant feeling,so when the engine is warm,the air-fuel ratio should not exceed 13.0. I'm about to cut it.

FCR Tuning - Change slow jet from 40 to 42 - 2022-10-08...
The other day,I changed the slow jet from 42 to 40. However,it seemed like we were reaching the limit of returning the PS,so we changed it from 40 to 42 again. For me,the boom now is to keep the air-fuel ratio at 12.5 to 13.0 when idling with the throttle fully closed. It feels like the ride becomes milder,which is good.
