Since you've arose this topic, might i ask the same question for myself here?
Okay here is the thing ...
YOu notice when you purchase a brand new bike Honda CG-125 Classic, listen to its Sound, you'll notice when you accelerate it a little bit, aawaaz chanak si jaati hay.
I CAN BET that when i purchased my used 2009 model of 125, it required tunning badly, its sound was just like a BRAND new Bike, VERY LOW, CLEAR, POWERFUL, and that same sound like i want, whoi Chanak daar si aawaaz.
I m sorry if its not much to make yu people understand, but how the hell can i get that sound back for my bike :S
Because it all started jab bike ki tunning ho gayi thi.
Now some people say its because tunning k doraan mechanic Filter ko Petrol say wash karte hain, and jab tak wo Petrol sookhta nahin hay, tab tak aawaaz sahi nahi ho gi.
Some say its because of the Silencer, where my Silence is still Genuine and THAT VERY SAME SILENCER was giving me the sound of a Brand New bike, aur ab jab kisi say poocho to bolay ga k SILENCER new dalwa lo :S ... i mean 1 common sense hay k agar silencer ka fault hota to pehle gaari wo brand new bike ki tarha ki chanak daar aawaaz na deti.
Now what to believe?
ANY EXPERT here, Please Tell us what is the main problem?
Its not a problem for me to get a new silencer, yea i can spend 1.6k to get another Genuine Silencer for Honda 125, but the problem is ... New Silencer Also require some Running, ta'kay iss ki jaaliyan Khul jayen aur gaari Khul k saans le. Because with a brand new silencer, you can't accelerate the vehicle more than usual.
