FCR tuning - Use BITO's default jet needle. I did a test drive with a higher cut-off....

I purchased a slightly special needle,90FXM,from BITO. What's special about it is that it's a count that doesn't see many upswings. In fact,it is not in the standard stock lineup. This is the needle attached to the current initial turning of BITO's CBX1000 FCR.

Comparison of FCR-jet needle cut-up. Let's take a look at the thickness of the small standard 90FXM and 90FTM....

I received the JN Jet Needle 90FXM from BITO. I have JN on hand with different tapers and different cut ups. I feel more and more like I'm buying it for experimenting rather than tuning it up.

tuning of FCR - If the small jet needle is F taper,you cannot choose the cut-up. Round up comparison...

I can't help but feel like the large is basically telling you not to use anything other than the E taper. Small has more overall numbers than large,but [E] taper still has more options. With F-taper,you cannot choose the cut-up unless you order it in units of 20 pieces.

CBX1000 FCR tuning jet needle replacement. Impressions from a test run after changing the taper angle...

When I started tuning up the FCR,there were two items that I thought I would avoid touching because I would get stuck in a swamp. Tapered angle and cut up. I thought it would be nice if I could just touch it lightly and see if it was in good or bad condition,but the more I touched it,the more I became concerned and couldn't help it,so I decided to try changing the taper angle. .

[FCR] Jet needles should be purchased from BITO....

I usually set the FCR with [F] taper. There is a symptom where it gets richer when the throttle opening is suddenly opened to 1/2. As a countermeasure,I tried various things such as changing the MJ main jet to a smaller size,but the feeling was not good,so I will try changing the taper angle to [E] and tuning it.

FCR tunings - all changes - 2022-07-09...

The theory of FCR turning is AB testing,one step forward,two steps back! After about a month of trying various things,I decided to completely change the turning. Rather than ignoring the theory,this is the first step in tuning it up. I've tried a lot of things and have a good history,so I changed everything in one go and started over.

Test run - Throttle opening 1/2 - MJ change - 2022-07-08...

This is about the CBX1000 FCR turning. I wrote about the results after replacing the MJ in my previous post,but I'll write about my impressions after a test run. I value test runs,but if you have an air-fuel ratio meter installed,you may get caught up in the numbers,so I try to be careful.

FCR - tuning - MJ and JN influence - 2022-07-08...

In the previous blogs,I was a little worried because when I started suddenly,there was a bump at about 1/2 throttle opening. The cause was the combination of the MJ main jet and JN slow jet. The reason for the judgment was that if the MJ was extremely lowered,it would not go away,but there would be a change.

FCR tuning - MJ main jet change - 2022-06-23...

Recently,the situation has become such that instead of tuning up FCR when I have time,I make time to set up FCR. I have to either calm down a little or get over it to the point where it doesn't bother me. Although it is called a main jet change,MJ and JN were changed.
