I removed and reinstalled the carburetor during the tuning process. Along with that, I also cleaned the motorcycle. There are mainly four things I do:①. Clean the chrome parts②. Polish the wheels③. Clean the exterior④. Apply silicone spray to the engine

FCR tunings - all changes - 2022-07-09...

The theory of FCR turning is AB testing,one step forward,two steps back! After about a month of trying various things,I decided to completely change the turning. Rather than ignoring the theory,this is the first step in tuning it up. I've tried a lot of things and have a good history,so I changed everything in one go and started over.

Test run - Throttle opening 1/2 - MJ change - 2022-07-08...

This is about the CBX1000 FCR turning. I wrote about the results after replacing the MJ in my previous post,but I'll write about my impressions after a test run. I value test runs,but if you have an air-fuel ratio meter installed,you may get caught up in the numbers,so I try to be careful.

FCR - tuning - MJ and JN influence - 2022-07-08...

In the previous blogs,I was a little worried because when I started suddenly,there was a bump at about 1/2 throttle opening. The cause was the combination of the MJ main jet and JN slow jet. The reason for the judgment was that if the MJ was extremely lowered,it would not go away,but there would be a change.

FCR tuning-Change Accelerator Pump diaphragm and test run...

I did a test run for about an hour during lunch time. My goal is to change the Accelerator Pump's diaphragm from the standard size to the small size,and see if the bumpiness that occurs when the throttle opens suddenly around 1/2 will be resolved. As a result,I feel like there has been some change,but it's unclear. Try widening the link lever plate and slowing it down as much as possible to see how the Accelerator Pump starts to work.

FCR tuning - Acceleration pump adjustment - 2022-07-06...

Since I had time to touch the motorcycle,I adjusted the FCR's Acceleration pump diaphragm. Even though it is an adjustment,it is just a matter of replacing the diaphragm. FCR's acceleration pump is an obscure and incomplete device. It is an unusual device that cannot be called precision like jets.

Is a quick turn throttle necessary for FCR?...

This is a story that always comes up when converting an old motorcycle into a racing carburetor. Since racing carburetors are intended for full-throttle driving on circuits,it is best to install a quick turn throttle. Depending on the purpose of use,there may be exceptional reasons not to install quick turn throttle,although it varies case by case.

FCR tuning - Lean slow jet - Changed from 48 to 40 - 2022-07-03...

This article is just about replacing FCR's SJ slow jet. Due to rain in the forecast,I decided not to do a test run and just replaced the SJ. SJ-48→SJ-40Actually,42 is probably better since it is the default value,but I want to verify the difference myself,so I replaced it with SJ,which is the lowest value than 42.

Comparison of bikini cowl and upper cowl...

定期的に走っているCB900Fと並べて写真を撮っていましたので、前回のブログに続けてカウルについてコラムとして書きます。カウルの取付に関してはビキニカウルやスクリーン、メーターバイザーなど、ボルトオンで比較的着脱が容易な物を前提に記載します。概ねヘッドライトのステーなどに取り付けるタイプです。

Do you install a cowl on your motorcycle?...

モーターサイクルにカウルを取り付けるべきかどうかをコラムとしてに書いていきます。私は先日、CBX1000にCBX400Fインテグラのカウルをオリジナルっぽくつけました。雑に結論から書くと、公道を走るモーターサイクルにはカウルは取り付けるべき！です。色々な観点で私見を書いていきます。
