New coils,,, bigger jets? was created by barquirt
Hi all.

OK spring is coming to MN soon, time to start my restoration project in earnest! First up is putting on a new ACCEL coil kit to pump up the spark. However, in doing this, will I need to bump up my pilot and main jet sizes a step or two? Adjust the air screws a tad? I have a 1977 KZ650B1 model.

Howdy, barquirt -- new coils should not require jet changes or mixture adjustments. Good luck with your restoration project! :)

I swaped in a set of new Black Dyna coils and spark plug wires. No change in jets. BIG change in performance.

Best of success with you B1.
