FCR Tuning - Regularly resetting the air screw and pilot screw can improve performance....

The FCR air screw and pilot screw are parts that can be adjusted continuously. In contrast, the slow jet and main jet needle can only be adjusted with specific sizes. The air screw is easily accessible once you remove the filter or velocity stack, making it straightforward to observe changes.

FCR Tuning - Having an air-fuel ratio gauge is useful for adjusting the pilot screw....

Having an air-fuel ratio gauge (A/F meter) is convenient for FCR tuning. Even without a gauge, you can achieve precise settings through real-world riding once you get accustomed to it. You can adjust mid to high-speed settings based solely on your feel. In fact, it might be better not to get too caught up in the numbers. However, it can be challenging to determine whether the throttle opening at low speeds is functioning well or poorly.

Does the scope of the FCR tuning manual affect the throttle opening or the valve opening?...

This is regarding the scope presented on page 8 of the FCR tuning manual. This page indicates the impact range of tuning, but it raises the question of whether the X-axis refers to the throttle opening or the valve opening. This is something I posted about recently; the throttle opening and valve opening of the FCR are not directly proportional.

FCR Tuning - To what extent does the main jet affect the throttle opening range? - 2023-09-19...

I'm describing the effects of changing the main jet, focusing on how it influences throttle positions other than full throttle. After changing the main jet, I went for a test run. My assessment is centered around the changes observed from around half-throttle to three-quarters throttle rather than focusing solely on the full throttle range.

FCR Tuning - Adjusting Accelerator Pump Discharge Timing and Straight - 2023-09-12...

I’m framing this as fine-tuning rather than tuning in the strictest sense. The tuning of the FCR is the result of repeated A/B testing. It’s a process of searching for jets that improve performance, and then finding even better jets from those improvements.

The throttle opening and throttle valve opening of the FCR carburetor are not directly proportional....

Even when the throttle is opened to 1/2 on an FCR, the throttle valve on the FCR does not open to 1/2. This is not specifically mentioned in the FCR tuning manual. Knowing this might change your perspective on the operation of the FCR throttle. At 1/2 throttle opening, the throttle valve is typically open only about 1/4.

With the quick turn throttle housing, you can set the throttle free play to 0mm!...

When installing a quick turn throttle, one feature that is not present in a standard throttle housing is the throttle stop screw function. Although it might sound elaborate, it is simply a screw hole that has been cut. It is a bolt used to adjust the minimum return position of the throttle.

Throttle grip wiring - The FCR is a push-pull carburetor. Its direct operational feel is very appealing....

For adjusting the throttle area, there's no problem at all in thinking that you can easily do it yourself without needing to rely on a professional. For such tasks, you can usually find methods by searching online. If you still have trouble, you can consult a local motorcycle enthusiast, and you’ll likely find a solution.

FCR Tuning - Testing 6 Variations of Accelerator Pump Diaphragm - 2023-08-22...

One of the highlights of FCR carburetors is the accelerator pump. This time, instead of making just minor adjustments, I performed tuning with all the diaphragms I have on the same day. The accelerator pump diaphragms tested were Standard, KLX250, and KLX400, with discharge timings of 1.0mm and 0.5mm, resulting in a total of 6 different patterns.

Adjustment of Motorcycle Throttle Free Play...

Throttle Free Play Basics. The standard throttle free play is typically set to 5mm. Additionally, it’s essential to ensure that the throttle returns properly when the handlebars are turned left and right. This ensures that the throttle operates correctly and safely.
