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 it is important to make comparisons. Often, you can't determine if it's good or bad just by looking at one thing. In the case of my CBX1000, I have installed an air-fuel ratio meter. You can judge the performance by looking at the numbers alone. However, if the instrument is misaligned, it can be a problem. The numbers should be used as a reference only, and tuning should be based on comparison of the changes made previously and currently. There is no end to FCR tuning. This season, I fine-tuned it to the point where it is okay for now.

I asked a friend to go for a test ride with me. Riding side by side with a friend can help you notice things. It can help you reaffirm that your tuning is excellent. I strive for the best tuning each time. However, sometimes my tuning is not good, and my bike ends up being slower than my friend's motorcycle. In such cases, I redo the tuning. You can find areas for improvement in what you thought was the best tuning at that time. Even I have had cases where I thought I had the best tuning, but it turned out to be a failure. Comparing allows you to realize such things.

It’s just a ride with two motorcycles.

I have my friend, who is equipped with an intercom, accelerate on a straight road while I follow, and sometimes I accelerate while asking my friend to follow me from behind. We perform the final check with only two bikes. I inform them in advance that we will include a test ride. If there is a mechanical issue, they help without any complaints. Conversely, when my friend does a test ride, I also assist them.

There should be new discoveries!

Receiving evaluations or feedback from others increases the likelihood of making new discoveries. Sometimes, you might not notice something for a while if you’re working alone. A simple comment from someone else can often resolve issues quickly. This is particularly true with FCR tuning, where preconceived notions can hinder progress. For example, I once failed to notice that the needle calibration on the multi-vacuum gauge I was using for carb synchronization was significantly off. Despite syncing the carbs, something felt off, and I ended up using four different gauges. It wasn't until much later that I realized the vacuum gauge balance was incorrect. I didn't know that needle calibration was necessary. If I had known someone with experience, I might have noticed it sooner. Consulting with friends can help you realize many things you might otherwise miss.

For beginners with FCR, it is important to remember the terminology for effective information sharing.

For beginners just starting with FCR tuning, sharing information is extremely important. If you have the chance to interact with an FCR veteran, you may be able to borrow tools or jets and receive assistance. More importantly, you might gain valuable information. You can receive guidance through the internet or social media. Knowing the terminology related to carburetors is crucial for effective communication during these interactions.

When meeting experienced FCR users, the key is whether you can share terminology and data, such as words and numbers. While you don’t need to memorize throttle openings or how to read jets, it’s important to keep a record of your motorcycle’s tuning history. You can ask questions about things you don’t understand, but it’s challenging for others if you don’t know what you don’t know.

Female FCR experts often go out of their way to offer thorough, thoughtful, and kind assistance. On the other hand, middle-aged men who love carburetors might not be as accommodating. Even if you don’t understand the FCR tuning manual, try reading it aloud at least once. This will help you start to communicate more effectively, including understanding the terminology.

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

Many people around me are into tuning and excessive DIY projects. The final check for FCR tuning goes smoothly when done with two bikes. While it's possible to do it alone, discussing tuning with others can make the process more engaging. There are many insights to be gained through conversation. Please be careful of reckless driving and enjoy your motorcycle safely. See you again!

CBX1000 – Photo Gallery

This time, I will include a photo featuring my friend’s CB900F. The CB900F was sold outside Japan and is a motorcycle that is not commonly seen in Japan. At that time, motorcycles over 750cc were not typically sold in Japan. The Japanese version was the CB750F.
