This article deals with the FCR settings for CBX1000, especially the PS pilot screw. In the article, 15 minutes = 90 degrees in clock notation. When returned, the amount of air-fuel mixture increases at low throttle opening. The basic return indicated by the manual is 1 return, and the adjustment range is 1/2 return to 3 1/2 returns, but it says to adjust so that it falls within the range of 3/4 return to 3 times return. .
FCR 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 FCR Tuning - Changing Slow Jets, Adjusting Air Screw and Pilot Screw - 2023-11-09...
It’s important to make adjustments to the FCR as soon as you notice something off. I’m considering adjusting the throttle low opening screw range and the air-fuel ratio at wide open throttle to be about 1.0 richer. I changed the Slow Jets (SJ) and Main Jets (MJ). This year, I decided not to change the SJ.

FCR FCR Tuning - If the pilot screw is set to 1.00 turns out, it may not be adjusted sufficiently....
In FCR tuning, the initial values for the screws are typically set to an air screw (AS) of 1.00 and a pilot screw (PS) of 1.00, as stated in the tuning manual. This content suggests that there might be an additional level of power available even after achieving what seems like the best tuning.

FCR FCR Tuning - Having an air-fuel ratio gauge is useful for adjusting the pilot screw....
Having an air-fuel ratio gauge (A/F meter) is convenient for FCR tuning. Even without a gauge, you can achieve precise settings through real-world riding once you get accustomed to it. You can adjust mid to high-speed settings based solely on your feel. In fact, it might be better not to get too caught up in the numbers. However, it can be challenging to determine whether the throttle opening at low speeds is functioning well or poorly.

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.

If possible, please check if the pilot screw is functioning correctly in this column-like post. If adjustment is difficult, fixing it at 1.00 turn out is also acceptable. Some people advise not to touch the pilot screw, while others recommend fixing it at 1.00 turn out. The pilot screw can allow the engine to idle even when fully closed.

FCR FCR Tuning - The pilot screw can be fully closed to allow idling....
Recently, I have been posting about tuning the FCR at low throttle opening. This time, it's about adjusting the pilot screw. There are many posts written about it depending on the time, place, and occasion. People say different things. The information provided also varies depending on the source, such as magazines and online articles.

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.
