FCR Tuning - Adjusting the air screw to the appropriate setting after changing the slow jet - 2023-08-13...

The position of the air screw has been adjusted to slightly less than 0.30 minutjes return. The pilot jet has been changed from 45 to 48. This air screw setting in summer may not be ideal for winter, as it would likely need to be adjusted (tightened) during colder months.

FCR Tuning - Tuning the main jet at full throttle is fun....

As you gradually open the throttle from a low position, you will adjust the relevant jets and screws. Once the low-throttle setting is in good condition, the main jet (MJ) is often already in a good or near-good state as well

FCR Tuning - Adjusting the Jets Slightly Leaner for Summer...

When discussing carburetor tuning, terms like "rich" and "lean" are often used. These terms can be a bit confusing for beginners.

FCR Tuning - Full Throttle! How lean can the main jet go? Will the engine hold up?...

I have performed full-throttle runs with a main jet size of 102 on my CBX1000.This is a discussion about how lean the main jet can be set based on past experiences.I should clarify that I haven’t tested it to the point of damaging the engine, and the testing is therefore insufficient. The inadequacy of the testing is due to the fact that it has not been tested until the piston melts.

FCR Tuning - Acceleration Pump Discharge Timing Adjustment - Finalized as is - 2023-06-20...

FCR Tuning for CBX1000. I was concerned about the discharge start position of the acceleration pump, so I conducted a test ride. As a result, I ended up making changes and then reverting to the original settings. There wasn’t much noticeable difference.

FCR Tuning - Test Ride with Awareness of Shift Position - 2023-06-17...

I'm still not quite able to tune it perfectly yet. Recently, I had the opportunity to ride on the highway. During the ride, I noticed something: I realized that I haven't been tuning with much attention to the shift position.

FCR Tuning - Adjusting throttle openings below 1/4 with the air screw, slow jet, and jet needle straight diameter - 2023-06-11...

This time, I will write about the air screw, slow jet, and the straight diameter of the jet needle from my perspective. This primarily concerns the throttle openings from about 1/4 to 1/2. Recently, I addressed and improved the issue where the throttle would hesitate during rapid opening—whether it was lean or rich was unclear. I will document the improvements made.

FCR Tuning - Jet Needle Clip Position and Accelerator Pump Diaphragm Replacement - 2023-06-10...

I was concerned about the throttle opening being less than 1/4, so I made some adjustments. Here’s what I did:①Changed the clip position on the jet needle.②Set the acceleration pump diaphragm to the standard output.I will discuss both points. There is an important note: do not perform these adjustments simultaneously.

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.
