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.

How much gasoline is accumulated in the float chamber of the FCR carburetor?...

For the FCR carburetor on the CBX1000, it holds about 100cc to 150cc. I took some photos when I changed the slow jet. I will be discussing how to handle gasoline when changing the main jet or slow jet on the FCR carburetor.

FCR Tuning - Re-synchronization after adjusting the throttle cable - 2023-08-01...

I synchronize the FCR carburetors on my CBX1000 more than 10 times a year. Whether 10 times is a lot or not, I’m not sure. It’s not that I feel the synchronization has drifted while riding and then correct it. Rather, it’s because minor misalignments occur when I perform tuning and have to remove and reattach parts.

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

Spark Plug Replacement - The Idling of Carbureted Engines Smells Like Gasoline...

If you feel that the idling is off, replacing the spark plugs and then re-tuning is a viable option. Tuning involves various interconnected factors, and the spark plugs might be one of the causes of irregular idling. By replacing the spark plugs, you eliminate one potential concern.

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.

3 Reasons Why Used FCR Carburetors Can Be Used...

When you perform the overhaul yourself, it generally ends up being quite cost-effective. This is specifically if you handle the overhaul personally. If you don’t have jets and other parts on hand, it's recommended to use the Carburetor Parts Kit for FCR - KEYSTAR. If you already have some FCR parts, you can buy individual parts separately and complete the overhaul that way.

FCR requires a filter for street use. Constant use of a velocity stack is not recommended....

This applies not only to FCRs but to all carburetors in general: going filterless on the street is not recommended. This is because it sucks in debris. I will write a column discussing why it’s better to avoid this and what you should do instead.

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.
