FCR-FCR tuning in general. 6 cylinder tuning, AS, JN, MJ replacement, etc.

FCR6 synchronization and fuel subtank...

I've been a bit off track lately with the idea of starting a motorcycle blog,but this is an FCR-related post. That said,it is related. As the title suggests,I would like to introduce you to the fuel sub tank. Rather than synchronization,I will write an introduction to the fuel subtank.

Three advantages of converting CBX1000 to FCR...

This time,I would like to introduce three benefits of converting CBX1000 to FCR,which is my favorite,by converting CBX1000 to FCR33. I will write about it in a column,but I will also introduce the disadvantages. There are no disadvantages caused by converting to FCR. Basically there are only good things.

About taper angle and FCR tuning - MJ confirmation from test run - How much does MJ influence? 2022-08-20...

Since today is Saturday,I wanted to ride on the CBX1000,but unfortunately it was about to rain. To shake or not to rain? Anything else? It was a subtle sky pattern. I ended up doing a test drive around my house while checking the weather forecast on my smartphone. So,I will be doing a test run mainly to see how the MJ looks after changing the tuning from last time.

About FCR-PS. Idle port,slow port and air-fuel ratio at idling...

The other day,when I was carrying around a Carburetor Pilot Screw Adjustment Tool,a certain mass touring group asked me,``What is this?'' ” I was bombarded with questions in turn. I have come to my own conclusions and done things that I had doubts about since I started tuning up FCR,so I will write about them historically.

What is the appeal of motorcycle carburetor specifications?...

There are two types of motorcycle fuel injection systems in the world. Carburetor specifications or other than Carburetor specifications? Except for the carburetor specifications,it will be injection. Since FCR is also a carburetor specification,I will write about the good and bad points of carburetor specifications while comparing them with injection. The trick here is to write about it while comparing it to injection.

FCR tuning - SJ and MJ change - 2022-08-15...

With SJ45,I felt like the screw was opening too much,so I changed it to 42. I chose 42 because I wanted to make fine-tuned tuning,but 40 might be the perfect range for all year round. I feel a little regretful that it might not be necessary to make it look strangely deviate from Bito's initial tuning.

Should I change the taper angle and cut-up of FCR? Check the number of clip stages first....

This time I will write in a column. The other day,I had a little conversation about the FCR tuning with the divine engineer who gave me two engines for my CBX1000 free of charge. I was told,``JN checks the number of clip stages before checking the taper angle.'' According to the master,it's natural that the clip position will change if you change the taper,so if you don't take that into account when purchasing a jet needle,it will be a waste of money.

FCR tuning - AS air screw adjustment - 2022-08-03...

I wanted to eat curry for lunch,so I went for a light FCR test run. With my ability,I can't decide on a good screw position in one go,so I just do test runs and try different screw positions from rich to lean.

FCR tuning - screw adjustment and AS Uotani SP2 dial tuning - 2022-07-29...

I looked at the cold startability of the engine and tried adjusting AS and PS. I had already decided on the general tuning the other day,so I didn't have to spend any particular time on it,so it was more of a confirmation process. I feel that it is better to open the PS for starting performance. I tried tightening and opening it,but in the end I left it at the default tuning and moved the idle stop screw a little higher.

FCR tuning - AS and PS adjustment during test run - 2022-07-28...

If you try to improve the starting performance,the PS will tend to open. Since it is a racing cab,you may not need to worry too much. Either way,I currently prefer a richer shade,so I'll see how it goes tomorrow morning. I'm thinking about various things,such as tightening the PS a little more and raising the stop screw a little.
