FCR Tuning - Tuning throttle opening from 1/16 to 1/8 - 2022-11-06...

Regarding the current FCR tuning of CBX1000,I was concerned about the lower throttle opening. It's not a good idea to get caught up in the air-fuel ratio meter,but a partial reading of 10.5 is around throttle opening of 1/16 to 1/8. It is unclear whether this condition is good or bad.

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 - Cold Startability - Air Screw and Pilot Screw Adjustment - 2022-11-01...

This is a post about the FCR tuning of CBX1000. The other day,I adjusted the air screw while watching the idling with a digital tachometer. I didn't tighten the pilot screw to rich or lean,and I didn't return the air screw for about 15 minutes after the maximum opening.

FCR Tuning - Adjust and synchronize air screw and pilot screw - 2022-10-27...

I tightened the pilot screw from fully open. I feel that there is no problem with rich when the throttle opening is slightly opened from fully closed,but too rich is not a pleasant feeling,so when the engine is warm,the air-fuel ratio should not exceed 13.0. I'm about to cut it.

FCR Tuning - Test run and screw adjustment - 2022-10-25...

My CBX1000 has a two-pronged throttle wire. There are two idling stop screws. Changing the idling will cause a slight loss of synchronization. It's only numbers 1 and 6,but I'm adjusting the idling stop screw while checking with the vacuum gauge.

FCR Tuning - Slow Jet Change - 2022-10-24...

When I did a test run the other day,I was a little concerned about the low throttle opening. The slow jet was set to 42 based on the time of BITO shipment. Perhaps it was because of the delayed discharge timing of the accelerator pump or because of the season,there were parts where the power was weak when starting from a fully closed throttle,and the air-fuel ratio was briefly lean,so it wasn't very pleasant. So I changed the slow jet from 42 to 48.

FCR Tuning - Trial run of pilot screw Slightly rich...

I did a test run of FCR tuning and took pictures of the rear area.If anything,the story is mainly about the test run.It's around 13 when idling,and I cut it down to about 12 with partial throttle pening.

FCR Tuning - Change slow jet from 40 to 42 - 2022-10-08...

The other day,I changed the slow jet from 42 to 40. However,it seemed like we were reaching the limit of returning the PS,so we changed it from 40 to 42 again. For me,the boom now is to keep the air-fuel ratio at 12.5 to 13.0 when idling with the throttle fully closed. It feels like the ride becomes milder,which is good.

FCR Tuning - Adjusting the Air Screw After Carburetor Synchronization - 2022-10-01...

I checked synchronization by touching it only with the throttle stop screw. I put the AS air screw back in for 5 minutes. I opened and closed the PS pilot screw for 15 minutes and checked the changes. There was a change in the startability of the engine,but as a result,I haven't made any changes since before I touched it. I did some light work on various things.

FCR Tuning - Test Run - Adjust AS - 2022-09-29...

I did a test run on the mountain road from 5pm. I changed my SJ the other day. The AS adjustment,PS adjustment,and idling adjustment will be done the next day,so I'll check the startability when it's cold. Since the SJ is being changed from 42 to 40,the plan is to open and close AS and PS about half a turn.
