If you want to reduce the vibration and sound of honda cg 125 classic pakistani model then you have to place a 16T teeth sporket at engine side front this will reduce the vibration in honda cg 125 pakistani model
Modification will be
16 t at engine and 38t rear wheel
Stock is
15t at engine side and 38 t rear wheel side
I also use a metalic bush with thin hole in it to reduce the sound when i needed more sound i simply remove that bush with a plyer plas and get again cg cracking sound
Along with that bush it sounds like suzuki gd 110 or gs 150 its ur choice open the hole more for more sound and less for less sound but not that much less which could eventually effect ur pick up
I made this bush from hot air soldering machine nozels which are easily avaible in electronic market in 50 rupees
