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.
