FCR Tuning - JN Jet Needle Straight Diameter and Clip Position - 2023-05-03...
Since changing the main jet, I’ve felt a power increase in my CBX1000. I’ve also been interested in trying changes to the slow jet and jet needle. I generally avoid adjusting the SJ (slow jet) when tuning the FCR, unless it’s beyond the adjustment range of the AS (air screw). For this reason, I decided to change the JN (jet needle).
