FCR Tuning - Cold Startability - Air Screw and Pilot Screw Adjustment - 2022-11-01...

This is a post about the FCR tuning of CBX1000. The other day,I adjusted the air screw while watching the idling with a digital tachometer. I didn't tighten the pilot screw to rich or lean,and I didn't return the air screw for about 15 minutes after the maximum opening.

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 Tuning - Apply filter oil to the Foam Air Filter Sock at the end...

This is not a story limited to FCR. While setting up FCR,I often test drive with Velocity Stack specifications. The reason is that it is a hassle to attach and detach the Foam Air Filter Sock when turning the air screw. Although it is a Foam Air Filter Sock,even if it is installed and driven with oil applied,it will not affect the settings much.

FCR Tuning - Adjust and synchronize air screw and pilot screw - 2022-10-27...

I tightened the pilot screw from fully open. I feel that there is no problem with rich when the throttle opening is slightly opened from fully closed,but too rich is not a pleasant feeling,so when the engine is warm,the air-fuel ratio should not exceed 13.0. I'm about to cut it.

FCR Tuning - Test run and screw adjustment - 2022-10-25...

My CBX1000 has a two-pronged throttle wire. There are two idling stop screws. Changing the idling will cause a slight loss of synchronization. It's only numbers 1 and 6,but I'm adjusting the idling stop screw while checking with the vacuum gauge.

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 - Slow Jet Change - 2022-10-24...

When I did a test run the other day,I was a little concerned about the low throttle opening. The slow jet was set to 42 based on the time of BITO shipment. Perhaps it was because of the delayed discharge timing of the accelerator pump or because of the season,there were parts where the power was weak when starting from a fully closed throttle,and the air-fuel ratio was briefly lean,so it wasn't very pleasant. So I changed the slow jet from 42 to 48.

FCR carburetor tuning - test run on the expressway and Kizuna Stadium in Iwakuni...

I have been told that a Saturday Night meeting will be held at Kizuna Stadium in Iwakuni from 19:00 on October 22,2022. Along the way,I also tried driving the FCR while checking various air-fuel ratio gauges and paying close attention to the effectiveness of the accelerator pump.

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.

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.
