Which is better, the Keihin FCR carburetor or the CRS carburetor? Of course, the FCR carburetor....

I’m writing a column comparing which is superior between the FCR and CRS carburetors. It’s not just a broad statement that the FCR is better because it’s a newer model. Instead, I’ve heard compelling explanations from professionals that should make you understand why.

FCR Tuning - Adjust the air screw to be slightly lean within the possible range, then adjust the accelerator pump - 2023-05-27...

I adjusted the air screw’s return setting and also changed the start position of the accelerator pump’s discharge. It’s been a while since I worked on the FCR. After a light morning ride with the usual 9F rider, I did the tuning.

FCR Tuning - Changing the Straight Diameter of the JN Jet Needle - 2023-05-09...

CBX1000 FCR Setting.Since last month, I have been gradually fine-tuning the settings. The idle and main jet are mostly decided. I’m focusing on the range affected by the straight diameter of the JN (Jet Needle), so this time I will change the straight diameter and take it for a test ride to see how it performs.

FCR Tuning - JN Jet Needle Straight Diameter and Clip Position - 2023-05-03...

Since changing the main jet, I’ve felt a power increase in my CBX1000. I’ve also been interested in trying changes to the slow jet and jet needle. I generally avoid adjusting the SJ (slow jet) when tuning the FCR, unless it’s beyond the adjustment range of the AS (air screw). For this reason, I decided to change the JN (jet needle).

FCR Tuning - Carburetor Synchronization - Is the Balance of Your Vacuum Gauge Correct?...

I will be writing a column about the zero calibration of vacuum gauge needles. To put it briefly, it's advisable to assume that the zero position of the needles on a four-bank vacuum gauge is generally miscalibrated.

Pingel Power-Flo fuel petcock for FCR – My favorite part...

I took some photos of the fuel petcock area in my rental garage, so I will write about that. It should be somewhat useful for those who want to introduce a Pingel petcock to older generation bikes. I like Pingel petcocks and have posted about them in the past.

FCR Tuning - Is an Air/Fuel Ratio Meter (A/F Meter) a Necessary Equipment?...

Is an air/fuel ratio meter (A/F meter) necessary for tuning the FCR on the CBX1000? Yes, it is. Even if you are not working with a CBX1000, an air/fuel ratio meter is essential for setting up a carburetor.

FCR Tuning - Main Jet Change - 2023-04-14...

This post is a continuation of the blog where I talked about the test ride after tuning the FCR on my CBX1000. The change to the MJ (main jet) has been confirmed to lean out the mixture, going from 125 to 120. Although I mentioned in my previous blog that I was unsure which JN (jet needle) to choose, I realized that there is no need to change the JN immediately. Therefore, I decided to start by changing only the MJ.

FCR Tuning - 2023-04-12 - Considering the Jet Needle Strategy...

The other day, when I used the CBX1000 to go to a motorcycle event, I spent a long time on the highway. This is a story about checking the FCR's performance in terms of riding dynamics. Although I say I checked it, my overall impression was that the feeling I achieved seemed to be quite rich.

Recently, I completed the front tire replacement for the CBX1000. Today, I finished the FCR synchronization work, replaced the spark plugs, and performed another round of synchronization. Additionally, I have also completed the preparation for an oil change. I replaced the oil filter and drained the oil.
