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.

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 Carburetor - The effects of the balance pipe...

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 - 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.

FCR - turning when installing Foam Air Filter Sock...

When tuning up an FCR,you will always run into problems such as the characteristics of Foam Air Filter Sock and Velocity Stacks. Is it better to add it? Is it okay not to wear it? What are the advantages and disadvantages? This time,I would like to comment on such questions as a rider who regularly uses Foam Air Filter Socks. I don't think it's the correct answer,but I think it has credibility as an opinion or way of thinking.

FCR-tuning luggage minimum...

This is the item I brought out for the FCR tuning of CBX1000. Do not carry excessive tools for unexpected situations,such as diaphragms and bolts for the main jet and accelerator pump,and clips for the jet needle. It fits in a small tool box. It's for storage,so it's not very strong,but I bought it at a 100 yen shop.

AS Uotani SP2-gap adjustment and iridium plug...

AS Uotani's SP2 has instructions to adjust the plug gap to 1.1-1.3mm. I've had some doubts about that. Is the same true for iridium plugs? This was a while ago,but I would like to write about the results of a phone call I made to AS Uotani.
