For the life of me, I can't find any reference on these forums or in my factory manual to the fuel trim screws on the ECU on my 2003 RSV. I adjusted these a few years back and got the synch nailed by going back and forth between the air bleeders on the throttle bodies and the trim pot adjustments on the ECU. But I can't recall (or find any reference in the manual) what does what on the screws? Is turning out richer or leaner? Which is front or rear cyl? I read about it somewhere, I thought in the manual but? Any help greatly appreciated!
