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.
