About FCR-PS. Idle port,slow port and air-fuel ratio at idling...

The other day,when I was carrying around a Carburetor Pilot Screw Adjustment Tool,a certain mass touring group asked me,``What is this?'' ” I was bombarded with questions in turn. I have come to my own conclusions and done things that I had doubts about since I started tuning up FCR,so I will write about them historically.

What is the appeal of motorcycle carburetor specifications?...

There are two types of motorcycle fuel injection systems in the world. Carburetor specifications or other than Carburetor specifications? Except for the carburetor specifications,it will be injection. Since FCR is also a carburetor specification,I will write about the good and bad points of carburetor specifications while comparing them with injection. The trick here is to write about it while comparing it to injection.

Even if it is not a CBX1000 cowl specification,some parts may be helpful for owners who want to install a frame-mounted cowl on a naked specification motorcycle. This is a duplicate of the previous article,but the content posted a while after installation and the post immediately after installation are slightly different.

In the case of a racing carburetor such as FCR,can it be run in the rain with a Velocity Stack specification? Should I do it?...

I hate driving in the rain. Working motorcycles and commuting motorcycles,including Cubs. Even large motorcycles shipped from the manufacturer are driven in the rain. Such motorcycles do not have any problems. After thinking about it for a while,I realized something.

tuning of FCR - If the small jet needle is F taper,you cannot choose the cut-up. Round up comparison...

I can't help but feel like the large is basically telling you not to use anything other than the E taper. Small has more overall numbers than large,but [E] taper still has more options. With F-taper,you cannot choose the cut-up unless you order it in units of 20 pieces.

[FCR] Jet needles should be purchased from BITO....

I usually set the FCR with [F] taper. There is a symptom where it gets richer when the throttle opening is suddenly opened to 1/2. As a countermeasure,I tried various things such as changing the MJ main jet to a smaller size,but the feeling was not good,so I will try changing the taper angle to [E] and tuning it.

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.
