Hey Bunny,
nice to know about your long ride. My only problem on long rides in my neck. Thigh and back are adjusted now. 19kmpl is very nice. I get around 18.8 on my long rides. I feel the reading the bike shows is pretty accurate.
Can you tell me which oil did you put exactly? Is it semi synth. or normal ?
And whats your jacket size ?

cause mine is too bog for me! even though I think my bro is gonna have it, still I feel its bigger for him as well...
Ive put extra premium full tanks a couple of times, and I have felt no difference in performance, except some knocking at low gears (1-2) on sudden acceleration.
