Which racing carburetor should you choose? FCR, TMR, TMR-MJN, CRS, or others…...

I will write about choosing racing carburetors based on my own biases. This is more of a column-type content and does not necessarily reflect knowledge from personal experience. Besides the Japanese-made racing carburetors mentioned in the title, there are also brands like Dell'Orto. As I love Japanese-made products for their easy parts availability, I will focus on domestic options and not cover foreign products.

FCR Carburetor Tuning - Slightly rich or too rich. It's best to keep it at a slightly rich level....

Regarding the tuning of the FCR carburetor on the CBX1000, my recent trend has been to tune it to a slightly rich setting. If the optimal air-fuel ratio is 12.5, I aim for around 12.0, considering that the mixture might lean out when the throttle is opened.

Is it easy for beginners to tune an FCR carburetor?...

FCRs have a wide tuning range and are said to be easy to set up... I sometimes see comments like this online, though I'm not sure how accurate they are. In my case, I've only worked on tuning FCRs for the CBX1000, so it's hard to say definitively. However, if you're doing rough and basic tuning, it is relatively simple.

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 - For street use, be sure to check the throttle response at the initial opening....

The FCR is a racing carburetor, but in reality, most users spend the majority of their time using it on the street. An important aspect in the street scene is starting. On the street, there are traffic lights, which means frequent stops and starts. On the track, once you start, there is rarely a complete stop.
