Follow-up. Bike waited a couple of weeks for 48K service and fast idle issue (a bit early for 48K svc as it is currently 45.3km, but I like to minimize the number of times it is in the repair shop). They evidently just cleared a number of error codes (approx 10) and it was OK. Errors included IA sensor, TP sensor,air temp sensor and even one that said "No DCT". So not sure what's up, but anyway it works just fine so far. I even feel the downshifts are a nuance gentler (the engine braking that is) but could be my mind playing tricks on me given the time I was without the bile. Anyway with respect to clearing such errors, that obviously limits and even discourages self-service on the bike, so certainly something to be aware of for "cost of ownership". Still, I'm relatively addicted to the sound, vibrations, handling and road presence/size of this bike. Had a CB1100RS loaner while mine was in the shop, and compared it has very few highlights, plus much too small for me.
