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 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 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 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 FCR tuning-Carburetor synchronization work-22/11/02...
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 FCR Tuning - Adjust and synchronize air screw and pilot screw - 22/10/27...
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.

CBX1000 FCR Tuning - Change slow jet from 40 to 42 - 22/10/08...
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.

FCR FCR Tuning - Synchronization -22/10/03...
When I went touring the other day,I touched the AS air screw,PS pilot screw,and idling stop screw,so I thought that the synchronization might be loose,so I made time to do it from 17:00 to 18:00. I synchronized while being careful not to be unable to work due to sunset.

FCR FCR Tuning - Re-synchronize and then adjust AS22/10/01...
I checked synchronization by touching it only with the throttle stop screw. I put the AS air screw back in for 5 minutes. I opened and closed the PS pilot screw for 15 minutes and checked the changes. There was a change in the startability of the engine,but as a result,I haven't made any changes since before I touched it. I did some light work on various things.

FCR Adjust the balance of the multi-vacuum gauge...
CBX1000 is a 6-cylinder multi-engine. You will need to synchronize the carburetor. The other day,I adjusted the balance of the vacuum gauge for the first time in a while. This time we'll be talking about multi-vacuum gauges for motorcycles. I don't know if it's for cars. Balance adjustment is to align the needles of each meter of the vacuum gauge uniformly. Whether or not the actual negative pressure can be measured accurately is another matter.
