List of tags related to FCR’s accelerator pump. I post a lot of FCR posts regarding CBX1000.
FCR Does the scope of the FCR tuning manual affect the throttle opening or the valve opening?...
This is regarding the scope presented on page 8 of the FCR tuning manual. This page indicates the impact range of tuning, but it raises the question of whether the X-axis refers to the throttle opening or the valve opening. This is something I posted about recently; the throttle opening and valve opening of the FCR are not directly proportional.

FCR FCR Tuning - Adjusting Accelerator Pump Discharge Timing and Straight - 2023-09-12...
I’m framing this as fine-tuning rather than tuning in the strictest sense. The tuning of the FCR is the result of repeated A/B testing. It’s a process of searching for jets that improve performance, and then finding even better jets from those improvements.

FCR FCR Tuning - Testing 6 Variations of Accelerator Pump Diaphragm - 2023-08-22...
One of the highlights of FCR carburetors is the accelerator pump. This time, instead of making just minor adjustments, I performed tuning with all the diaphragms I have on the same day. The accelerator pump diaphragms tested were Standard, KLX250, and KLX400, with discharge timings of 1.0mm and 0.5mm, resulting in a total of 6 different patterns.

FCR How much gasoline is accumulated in the float chamber of the FCR carburetor?...
For the FCR carburetor on the CBX1000, it holds about 100cc to 150cc. I took some photos when I changed the slow jet. I will be discussing how to handle gasoline when changing the main jet or slow jet on the FCR carburetor.

FCR Does the CBX1000 require an FCR accelerator pump?...
I'm writing about whether the CBX1000 needs an FCR acceleration pump. I want to make effective use of what I can use. Keihin also uses this mechanism because it is necessary. It is said that single engines such as the SR have too much total discharge. I think that the timing of the start of discharge should be decided more strictly than the total discharge amount.

FCR FCR tuning - I bought an acceleration pump diaphragm so I'll compare the sizes...
I bought an acceleration pump diaphragm for the KX400 to set up the FCR of the CBX1000. As of November 2022,the price should be 1,892 yen for two pieces. I don't remember exactly because I bought them together with other items. I should mention in advance that I only bought them and have not compared them since installing them.

FCR 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.

FCR FCR tuning - You can tell whether the accelerator pump is rich or lean with the air-fuel ratio meter....
My CBX1000 is equipped with a PLX DM-6 air-fuel ratio meter. When it comes to measuring the air-fuel ratio meter,which is the subject of this article,it is better to use one with a wide band and high response. I removed and installed the CBX1000 triple meter analog voltmeter.

FCR CBX1000 photo and FCR acceleration pump discharge timing turning...
I rarely ride my bike without thinking about anything. I think it would be more meaningful to make some changes to the FCR before riding the bike. I've gotten into the habit of touching something before I run by myself. I will post a photo from when I took a test run by myself at Yasunohana Station the other day.
