Had my R77 full system dynoed about three weeks ago. Readout shows that A/F ratios were all over the shop. Horsepower is now up, but more importantly, A/F ratio is much better so bike has to be running better across the entire rev range (I can't give a seat of the pants account because I got dyno done straight away so haven't anything to compare with).
Every bike comes out of the factory with different A/F ratio, so it is best to optimise this on an individual basis for your bike.
AS for running lean to comply with ADR's. ADR is done at a specific rev range, so it may be lean there, but rich somewhere else then lean again. As I said, mine was all over the place.
