CBX1000 FCR settings. Special mention is made of the air screw. The number of returns is expressed in clock notation. If you go back 15 minutes, it will be 90 degrees.
FCR FCR Tuning - Adjusting the air screw to the appropriate setting after changing the slow jet - 2023-08-13...
The position of the air screw has been adjusted to slightly less than 0.30 minutjes return. The pilot jet has been changed from 45 to 48. This air screw setting in summer may not be ideal for winter, as it would likely need to be adjusted (tightened) during colder months.

FCR 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.

FCR FCR Tuning - Changing the Straight Diameter of the JN Jet Needle - 2023-05-09...
CBX1000 FCR Setting.Since last month, I have been gradually fine-tuning the settings. The idle and main jet are mostly decided. I’m focusing on the range affected by the straight diameter of the JN (Jet Needle), so this time I will change the straight diameter and take it for a test ride to see how it performs.

FCR FCR Tuning - JN Jet Needle Straight Diameter and Clip Position - 2023-05-03...
Since changing the main jet, I’ve felt a power increase in my CBX1000. I’ve also been interested in trying changes to the slow jet and jet needle. I generally avoid adjusting the SJ (slow jet) when tuning the FCR, unless it’s beyond the adjustment range of the AS (air screw). For this reason, I decided to change the JN (jet needle).

FCR FCR Tuning - For street use, be sure to check the throttle response at the initial opening....
The FCR is a racing carburetor, but in reality, most users spend the majority of their time using it on the street. An important aspect in the street scene is starting. On the street, there are traffic lights, which means frequent stops and starts. On the track, once you start, there is rarely a complete stop.

There are various owners when it comes to tuning FCR, ranging from those who want it to be perfect to those who are satisfied with around 80% accuracy. Among them, many owners prefer to adjust the FCR only within the range they can access.

FCR FCR Tuning - The air screw is set to one turn back as a baseline. How much should it be adjusted?...
CBX1000のブログを書いている事がきっかけで、知らない人からエアスクリューの戻しの調整について、色々教えてくれとリアルでご質問を受けました。365回ブログを書くという事を目標としていて自分の為にブログを書いているのですが、ブログから反応があると嬉しい物です。

FCR FCR setting - proper air screw value...
I think the proper way to return the air screw is about 1.5 turns. When I first started playing with the CBX1000 FCR, I changed the slow jet a lot. When I didn't know how to tune it, I just changed everything I could get my hands on. Now I'm trying to avoid changing the SJ as much as possible.

FCR FCR Settings - How to adjust the AS air screw and PS pilot screw...
I will write about my own method of adjusting the FCR screw for the CBX1000 FCR setting. There may be better ways, but this may be useful for CBX1000 owners who are just starting to set up their FCR. In my opinion, adjusting and synchronizing the screws on a 6-cylinder engine is more of a hassle than it is difficult.

FCR FCR Tuning - Throttle opening 1/16 determined by straight diameter and slow jet...
This is a story about when I used a jet needle that I bought a few years ago for setting the FCR of my CBX1000 but hardly used. The other day, I looked back at the past logs about the changes in the straight diameter of the SJ and JN. My experience is different from that of my past self, so the accuracy and precision of what I have written down will be different.
