Tags for articles that include FCR settings, especially SJ slow jets. This is a jet that mainly controls fuel supply at low throttle openings. For the SJ area, detailed adjustments are made separately using the AS air screw and PS pilot screw. Depending on the size of the SJ, if the return range of the screw does not correspond to the appropriate position, replace it.
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 - 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 - 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.

The other day, when I used the CBX1000 to go to a motorcycle event, I spent a long time on the highway. This is a story about checking the FCR's performance in terms of riding dynamics. Although I say I checked it, my overall impression was that the feeling I achieved seemed to be quite rich.

This is a description from the history of CBX1000 FCR tuning. It may not be useful, but if you intentionally unbalance the jet, you can use a jet that you can't use. In particular, the CBX1000 tends to run out of clip stages.

I received an email asking about the FCR of a CBX1000. I'm an amateur, but I try to provide information diligently in my own way. I'm not doing this commercially, but I'm very happy when I get a reaction from the web. This time, I'll write about the order in which you should tune the FCR from the factory.

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 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.
