    Default Cg 125 gear jerk...?

    Bike is cg 125.

    Problem is when i release the throttle, there is a jerk, as if there is too backlash. A clunking sound is also heard when the jerk is considerably stronger. Chain tension is ok, rear damper bushes are replaced a while ago.

    Seems to me that there is too much play in the gears... please comment!

    Its classic 06' model.

    The jerk is there when the engine start engine braking that is when the throttle is returned. Feels like there is backlash in gears and it engages in the other direction with force and may be it slips the clutch a little so making a "dug" sound.

    Oil: Havoline, and level does not fall till next oil change.
    Driven: too much, (no record/history)
    Changed: Chain-Sprocket set, clutch. Previous history unknown.

    I have bought it few months back. Changed the chain-sprocket set with the damper bushes on the first day and later changed the clutch. At the time of clutch change the mechanic said that the slight gear "ghar ghar" noise at higher speeds is due to some gear that is not genuine. I asked if we replace it, he said the new part will have the same noise so let it be like this. sometime after clutch change i started to notice the play in gears. May be it was there before but did not noticed.

    @metalhead! kindly check and inspect the sprockets, transferring power to the rear wheel. I am pretty sure its worn out sprockets causing this problem.

    Chain sprocket set is new. I will check it and the bushes too. But the mechanic said its the clutch drum gear and its pinion or something like that or he said it could be the clutch drum wear...
