Changed the FCR acceleration pump diaphragm. Visual inspection is important. Changes in total discharge volume are difficult to understand...

I am trying to replace the FCR standard accelerator pump diaphragm with the Kawasaki KX250 diaphragm. There is a dot in the center of the accelerator pump that suppresses the movement of the accelerator pump diaphragm. As for how much of a change there is,you can feel the change when you see it for the first time.

Tools required for CBX1000 FCR tuning...

Racing carburetors such as FCR are not finished once they are installed; with FCR,it is just the start. FCR starts after tuning. This time I will introduce the tools used for FCR tuning of CBX1000. It will also serve as a reference for other motorcycle FCR users. The main focus is on tuning,so if you want to completely disassemble it you will need a separate tool,but this is an introduction to tools for tuning.

FCR tuning - jet needle clip stage number change - 2022-10-16...

CBX1000 FCR tuning. Even though I say I will tune it,I am very satisfied with the current situation,so I am changing it for the sake of knowledge. The number of clip stages has been changed from [2] to [3]. Very good. The number of clip stages will be set to [3] for the time being. If you change the number of clip stages from season to season or over time,you will often find that the ride quality of your motorcycle changes significantly and becomes better.

FCR Tuning - Trial run of pilot screw Slightly rich...

I did a test run of FCR tuning and took pictures of the rear area.If anything,the story is mainly about the test run.It's around 13 when idling,and I cut it down to about 12 with partial throttle pening.

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.

FCR-PS Isn't it too rich? How to decide between pilot screw and slow jet...

I've been worried about something ever since I started using FCR. This is how to return the pilot screw. The other day,when I was synchronizing,I noticed something,so I'll write it down. There are few people who specifically write about how to decide on slow jets and pilot screws.

FCR Tuning - Synchronization - 2022-10-03...

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 Tuning - Test run after changing MJ main jet...

I drove on the expressway. Speaking of expressways,for those who regularly tune FCRs,there is only one thing to do. Check MJ main jet. Driving at full throttle. In terms of throttle opening,the range of MJ influence is from fully open to close to fully open. The CBX1000 has up to 5 gears.

FCR Tuning - Changed SJ from 38 to 40. PS pilot screw adjustment - 2022-09-28...

① Set the AS to a slightly richer position. ② Set the PS back by 1.00 minutes. ③ Open the PS for about 15 minutes at a time. ④ Open the PS to a point where it is easy to maintain idling and it is finished. In the case of CBX1000,I have never had a problem with driving because the PS was opened too much and it was too rich,but I start from a lean PS and then richen it.

Since I changed the FCR - SJ, I checked the startability and touched the PS - 2022-09-28...

There are various resets to ensure a comfortable ride. Generally,after changing the SJ,there are many work items as it involves attaching and detaching the cab. ① Adjust the tension of the throttle wire. ②Adjust the PS so that the engine can start. ③Temporarily adjust AS. ④Adjust the idling. ⑤Synchronize. ⑥Take a test run and adjust AS. Adjust the above by going forward and backward through steps 1-6.
