ive recently got my honda dio bored
and it was fine till 5000kms after bore and recently it started to give white smoke from silencer when it goes above 60 or when i raise suddenly.
i went to mechanic n he said that the piston rings n the head guide and a valve is gone so i replaced them also
but still the smoke from silencer comes and i am concerned about smoke as i have got it bored and not less than 5k kms were clicked


so what could be the problem guys
