Test drive the CBX1000 and head to the rental garage...

I didn't return it to the rental garage for a while because the rainy season ended and it was easy to drive,and I was frequently tuning the FCR. The day before I ride the CBX1000,I pull it out of the rental garage,leave it at home,and ride it the next day.

FCR tuning - SJ and MJ change - 2022-08-15...

With SJ45,I felt like the screw was opening too much,so I changed it to 42. I chose 42 because I wanted to make fine-tuned tuning,but 40 might be the perfect range for all year round. I feel a little regretful that it might not be necessary to make it look strangely deviate from Bito's initial tuning.

Comparison of idle port and slow port of FCR carburetor...

I hadn't been aware of it until now,but this is a story that makes me feel like I understand the difference in air-fuel ratio between the idle port and the slow port. There was an incident where I was able to see the difference between fully closing the throttle and opening it slightly to about 1/16,so I will write about it. First of all,I would like to disclaim that I am a programmer by trade and not a motorcycle shop staff member,so please understand that I may contain incorrect information or expressions.

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.

Verifying the impact of CBX1000 PS...

This is a blog post where I tried restoring the PS of CBX1000's FCR. PS is active when idling. It works at least at rotation speeds of 1300RPM-1500RPM. It may be that after a certain level of concentration (returning the PS) there will be almost no effect.

pilot screw adjusting tool. One of the things I always worry about when using a CBX1000 is how to turn the pilot screw. I've tried about 3 pilot screw adjusting tool so far,but I haven't been able to find the perfect one.

FCR-Synchronous screw nut limits and SEP bearing guide...

The article says there are limits,but the article is not saying that there are limits to synchronization,but rather that if you synchronize several times,you will reach the limit of the adjustment range,so you will need to reset it. This will be a blog post. This is a story that people who don't have anything to do don't have anything to do,so please read it quickly.

FCR-Balance pipe effect

This is going to be a bit of a rough article. I've been wanting to check the operation with and without a balance pipe for a while now,so I'd like to post about that. I will write the results first. [No change] The verification method is sloppy,and I don't know if the thickness of the balance pipe is the appropriate size in the first place.

FCR-Drain bolt O-ring replacement...

Drain bolt O-ring replacement for FCR33 pie. It was leaking gasoline,so I replaced it immediately. The symptoms did not improve even after replacing the chamber gasket,so I fixed it by replacing the O-ring on the drain bolt.

FCR - Synchronization - Taper Gauge...

The suction force for each cylinder is slightly different,but even if you just match it with the taper gauge,the synchronization is good. Although it is far from perfect,there are two points below: (1) The engine does not idle at high speeds when it warms up. (2) The tachometer returns extremely poorly when racing.
