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

I want to synchronize the FCR carburetor myself after installing it....

Whether it's a CBX1000's six-cylinder or any multi-cylinder carbureted motorcycle, if you own one, you'll likely want to handle the synchronization yourself. Standard vacuum-type carburetors are not frequently tuned, so many people leave this task to professionals.

FCR tuning - It is easier to make a judgment if you do the final check by test riding with two motorcycles....

When tuning the FCR on the CBX1000, I believe that comparing is important. Often, it's not possible to determine if something is good or bad based on just one factor. In my case, since I have an air-fuel ratio meter installed on my CBX1000, I can judge the performance based on the numbers. However, if the gauge is even slightly off, the readings may not be reliable.

FCR Tuning - Please check if the pilot screw is working correctly...

If possible, please check if the pilot screw is functioning correctly in this column-like post. If adjustment is difficult, fixing it at 1.00 turn out is also acceptable. Some people advise not to touch the pilot screw, while others recommend fixing it at 1.00 turn out. The pilot screw can allow the engine to idle even when fully closed.

FCR - Once you have installed Quick turn throttle, change the tuning accordingly...

Do you need a quick turn throttle? Or not? The answer is rider preference. But it does add one more thing to your riding. You can open the throttle fully by twisting it once. This is something you can't do without a quick turn throttle.
