I was busy in Eid Holidays so couldn't respond earlier.
Well, the first tuning and the whole experience of it including post-tuning was pretty interesting in both positive and negative sense.
First tuning was done when the odo-meter was 997. First of all, all the ravi service centers denied offering free tuning, I was like what the ... anyways, it didn't bothered me much so went for a tuning.
After the turning, the vibrations of bike reduce significantly - especially between the speed of 55 to 70. as below 55 and after 70, vibrations were otherwise minor - but vibrations are there.
After the first tuning, one more thing started to happen. Once I reach to the speed of 70 or 80 and if I leave the throttle, after a few seconds while speed is decreasing, the bike create a noise like it has missed a stroke. Sound like tuss... It happens 7 out of 10 times. I believe, I need to change the plug as it seems like the issue.
Afterward, I pushed the bike on an empty road (on 9th Avenue in late evening last sunday) and bike reached to the speed of 85 easily but then it struggled to reach the speed of 90 and after about 2 minutes on full throttle, it managed to reach the speed of 95 while sitting normally like heads-up. I'm not into junk like stunts anyways. All mentioned speed were of speed-o-meter which I am not sure is accurate. Then I reduced the speed as I was getting the impression that bike will explode. 
So, this was an interesting experience.
Apart from that, this time I poured zic 10w40 oil - 0.7 liters as almost everyone told me that book has mis-printing (where it says we need to pour 0.8 liters) and I'm having no issues with 0.7 liters of oil.
So far, fully satisfied with this bike.
