Aprilia Caponord ETV 1000 Perfect Fueling

After modifications to the O2 sensor for my AFR gauge I can accurately adjust the fuelling for the perfect 14.7:1 ratio. When I first placed the tube down the cans it was at 12.0:1 so very rich, and I've ended up adjusted the long term fuel trim a have the figure in the ball park ,see footage. edit, I've now added a little more fuel to my trim to have the AFR value at 13.5:1 which seems to be a good compromise for a steady idle and still better than before at 12.01:1 , so i still expect better MPG . LTFT was set at 5.7% to achieve AFR 13.5:1 at idle . This bike has the swordfish map and has LeoVince SBK exhaust cans fitted with the baffles in. Also I've achieved 55 mpg with this set solo riding with no luggage on back roads so that's potentially 300 miles u.til dry on a full tank .UK mpg
