I have adjusted my WUR to have these AFR's with the IA modified fuel head when warmed up:
Around 14.5:1 at a steady 30-40mph cruise for decent gas mileage.
Around 13.9-14.1 at idle. Just about exactly where I have mine set. 14.2 steady cruise, 13.8 to 14.0 at idle. And I still have the stock fuel head and cams.

The modified flowtech IA fuel head and B.L. adjustable WUR were almost $1000 together and that plus the AFR gauge and rpm switch/vacuum solenoid and time spent adjusting things over and over are enough time and money spent on the AFR subject for me.QUOTE] Well said Jim! Before I started adding all the CIS "bandaids" and on-board AFR gauges, I felt better. Now, I've got too much information, forcing me to always seek the perfection that CIS will never deliver. Sometimes too much information is too much.
