FCR Settings - How to adjust the AS air screw and PS pilot screw...

I will write about my own method of adjusting the FCR screw for the CBX1000 FCR setting. There may be better ways, but this may be useful for CBX1000 owners who are just starting to set up their FCR. In my opinion, adjusting and synchronizing the screws on a 6-cylinder engine is more of a hassle than it is difficult.

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 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.

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 Tuning - Jet needle changed to 90FTN. I was concerned about the straight diameter - 2022-11-15...

This is a test run after changing the jet needle of the CBX1000 FCR. The purpose is to check whether the straight diameter of the jet needle is good or bad at low throttle opening. I have been selecting a jet needle for the slow jet 48 for a while now. As a result of the test run,the acceleration is so good that I don't want to touch it for a while.

CBX1000 is a forced open/close type gasoline cock. About the fuel line Although it is a short path during the process of sending fuel from the gasoline tank to the carburetor,air may become trapped. It's not just the angle of the fuel line,but also the nature of the filter that makes it difficult for fuel to flow.
