Anyone had this error code 3A1570 Mixture Preperation Adaption Bank 1?
Engine on idle is lumpy. If you just touch the throttle it seems to miss. Other than this bike runs excellent. Error code is stored in memory and is not bad enough to put MIL light on dash. I’ve removed plugs and on cylinder 1 they are black running rich. Cylinder 2 top plug is perfect bottom black?
Removed O2 sensors and both test ok.
If you delete codes. Bike will tick over ok until you go for a ride and issue comes back and code is stored again. HELP…………
