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.

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 - Acceleration Pump Discharge Timing Adjustment - 2022-10-12...

The acceleration pumps of the old CBX1000 FCR are attached to numbers 3 and 6. Looking at the range of influence in the tuning manual,it is in 0.6mm increments,but there are individual differences between vehicles and FCRs. Or,the tabs may become strange due to over-adjustment,so it is better to check visually to some extent and use this as a guideline only.

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 Tuning - An Easy Way to Turn Off the Accelerator Pump...

All you have to do is clip the push rod of the accelerator pump to prevent it from moving. I will also add a photo,so please check the size and position of the clip. For those using the old CBX1000 FCR,there are two carburetors.

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 - Acceleration pump adjustment - If it is too fast,it will hit the throttle valve....

Write down what will hit you first. I found a case the other day,where the fuel injection from the FCR's accelerator pump hit the throttle valve. The fuel is not being sucked into the engine,but is instead hitting a door called the throttle valve.
