I have driven almost 5 to 600 after that change. Economy is somewhere around 60 kmpl. Pick has certainly improved, not sure about engine noise .... maybe Hassan Abbas Sb is right to this extent that engine sound is a bit increased, although just after the change, I was of impression that bike has gone soundless, but in later stages and after just thinking alot about the engine sound, maybe it didn't get quiet that much I was expecting it to get. But, till date I can feel not very much noticeable difference in sound. Yes gear shifting was hard but that was due to improper clutch adjustment, I got my bike tuned day before yesterday. Will post the results afterwards regarding the gear shifting. Top speed k khwaab dekhna chor diye mein ne and I have told myself that just enjoy smooth, noiseless and economical ride. Don't expect much, let 125 and 70 ppl enjoy the speed dominance. Day before yesterday the mechanic has also disturbed carb screw settings, let's see what are the results I get after his "ustaadi", if I won't face much economy and missing issues, I'll just stick to that.
I got my first oil change (Yamalube) on 350 odd. Then I drove that Yamalube for another 1,000 Km approx. I changed liqui moly on 1,400 (1,050 + 350 KM) and now my bike is above 2,000 KM driven. On 2,000 KM I got my bike tuned but no oil change
