FCR Tuning - Where should I tune the main jet at full throttle?...

This is about the main jet settings for the CBX1000. You may not need to worry about this too much on a small motorcycle, but where should you set the main jet on a large motorcycle? There is only one answer. [Chassis dynamo] Nowhere else to do it other than on the chassis dynamo. You can sign a contract for about 200,000 yen per month.

Selecting a jet needle for the CBX1000 FCR model - I want to choose something other than the 90FXM...

The current CBX1000 FCR jet needle shipped by BITO is apparently 90FXM#3. I called to ask. The 90FXM has a special cut-out with an [X]. Normally it's [T]. I don't want to change the taper angle, but I'd like to change the straight diameter in various ways, but there are no options.

Riding is fun when you attach a cowl to a naked motorcycle...

Driving review with CBX400F Integra cowl installed on CBX1000. I am not talking about how easy it is to drive without the wind,or how it looks,but it is a lot of fun to throw it around and knock it over. My riding technique is rather poor. And if anything,it feels like a straight line number.

Does the CBX1000 require an FCR accelerator pump?...

I'm writing about whether the CBX1000 needs an FCR acceleration pump. I want to make effective use of what I can use. Keihin also uses this mechanism because it is necessary. It is said that single engines such as the SR have too much total discharge. I think that the timing of the start of discharge should be decided more strictly than the total discharge amount.

FCR tuning - I bought an acceleration pump diaphragm so I'll compare the sizes...

I bought an acceleration pump diaphragm for the KX400 to set up the FCR of the CBX1000. As of November 2022,the price should be 1,892 yen for two pieces. I don't remember exactly because I bought them together with other items. I should mention in advance that I only bought them and have not compared them since installing them.

Notes on changing FCR slow jet...

Since the CBX1000 has 6 carburetors,the number of jet changes is 6 times that of the SR,and 1.5 times that of a 4-cylinder motorcycle. It's a pain. When purchasing a new jet,it costs 6 times more than an SR. I don't regret it too much since it's money I'll be spending on my hobby,but it's better if it doesn't cost anything.

FCR Tuning - Slow Jet Selection - Start with the pilot screw back at about 1.0 turn...

You should be careful when choosing a jet needle. Even if the condition is good when the throttle opening is low,the effect may appear as the throttle opening is increased. The number of CBX1000's FCR jet needles at the time of shipment is 90FXM#3. The cut-up is special.

FCR Tuning - Apply filter oil to the Foam Air Filter Sock at the end...

This is not a story limited to FCR. While setting up FCR,I often test drive with Velocity Stack specifications. The reason is that it is a hassle to attach and detach the Foam Air Filter Sock when turning the air screw. Although it is a Foam Air Filter Sock,even if it is installed and driven with oil applied,it will not affect the settings much.

Tools required for CBX1000 FCR tuning...

Racing carburetors such as FCR are not finished once they are installed; with FCR,it is just the start. FCR starts after tuning. This time I will introduce the tools used for FCR tuning of CBX1000. It will also serve as a reference for other motorcycle FCR users. The main focus is on tuning,so if you want to completely disassemble it you will need a separate tool,but this is an introduction to tools for tuning.
