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 - 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.

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.

What are the disadvantages of a racing carburetor? - Regular maintenance is required....

I will be writing a column about the necessity of maintenance for racing carburetors. Please understand that my views may differ from conventional thinking. It’s likely that many people use racing carburetors in street applications without much consideration.

Work at the rental pit on 2023-03-25 - Installing the FCR and removing the front tire...

This is part of the winter maintenance work on my CBX1000. The plan for today was to replace the vacuum release plate and complete the synchronization work, but due to an easy mistake, I drained the battery. I’ve changed the plan to get the work done up to just before the synchronization and also complete the removal and installation of the tires.

Winter Maintenance on the CBX1000 - I’m gradually progressing with the work at the rental pit. It’s better than not making any progress at all. I tried to get as much done as possible, even if it was just for an hour. The tasks completed so far include removing the FCR carburetor and taking out the throttle valves inside it.

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.
