I have a 2013 cg125 model. I just had a new clutch plates, pressure plates, Valves (lait machine stuff), new piston (Crown Liffan). Now the bike runs like a new 125 but when it gets heat up after some miles it starts to do knocking. The ride doesn't feel like the same anymore. The pickup is good everything is good but for example speed breaker comes and I apply the brake I must change my gear to the 1st otherwise if it is not very slow still it does knocking. Whereas when I start the bike first time early in the morning, there is no knocking sound. The knocking sound also can be heard when we increase the accelerator from the zero even when the bike is not in gear. I am really really upset. Please help.
PS: The problem i'm having is only when the bike is heated up, doesn't matter if we drive it or not but when it gets heat up it starts to do this knocking problem.
