    i think you should open the head to check whether it's piston or connecting rod because come to any point right now is not right
    but this thak thak can also be caused by broken ring and wrong timing

    Noise is too damn loud for cam gear if it's really cam gear then there is too much play in it I suggest to get new cylinder as the housing of old one seems bad

    Oversized pin will do nothing if housing is worn out

    if your machinist did not reassemble the crank back to true perfect alignment of the crankwheels - then the drive gear on the axle of the crankshaft assembly which you are calling "weight" - will run off center and chew up the cam gear wheel too which will then make the "crying and whining noise" and when it gets worn down quite a lot it will start to hammer the pin on which the cam wheel spins.

    To remedy this, the crankshaft assembly needs to be balanced with a dial gauge to make sure its axles are dead straight. If your machinist or mechanic did the balancing with a hammer and a couple of V blocks while eyeing the shaft, there is a 75% chance the crankshaft is not true and will cause noise. If you dont believe this then get some prussian blue which is also called gear marking compound and use that to see the misalignment on the gears.

    When installing the new items a bit of high pressure assembly lube is advised to prevent dry run damage.

    Design of Honda 125 engine and today's poor quality if metal used are responsible for such noises in the engine.
    You do what ever u can, i mean change all relevant parts like weight bearing, cam, cam gear, cam shaft, cam follower pivot shaft l, push rods, rocker assembly, valve, valve sleeve, valve seals, complete clutch box and drive gear etc with few hundreds of KMs the noise will come back.
    Recently I purchased zero meter with 2017 model sticker and have derived only 520Km but tic tic sound, clutch gears kee kee sound, and to some extent cam gear noise have started.
    Although i have not crossed the speed of 50 with single person till now. Oil changed liqui moly on 300KM.
    Now what you people say about quality of this machine.
    I have shifted from Suzuki Sprinter 110cc, 2006 model. Believe me still sound like zero meter bike quite quiet. Driven more than 140000 km and only once engine overhauled.
    Now lets see what this Honda will do with me.

    sounds like a half way assesment, did you do any measurable analysis on the metallurgy or are just repeating what mechanic told you?

    Yes. I did many experiments myself. In fact in my college life (1991), having bike but no big pocket money, enforced me to learn to cop with engines.
    Every friday was bike operations day with group of friends.
    Aah sweeeet memories.

    nice.

    I have been in the same boat - and saw a lot of CG125E engines with this exact problem.. I just used some best practice ways to measure gear alignment (just like checking engage point of pinion to crown gear in diffy of a car).. I found that balancing the crank with a dial gauge to have the best result - just like the Honda service manuals tell you.
