    there is a breather vent on the engine crankcase - its hidden behind the upper engine bolt inside the chassis metal, if its dislodged it will make a "puffing"

    This vent is also found on CG125 but its exposed, to get to the CD70E engine vent you need to remove the engine.

    The really old CD70E models (first to about mid 80s) had the vent that shoots out into the magneto cover from a little hole.

    !!! Solved my issue !!!

    Two days ago i went to Rawalpindi on bike from Jhelum and the bike was used too much it was minimum 250kms that i drove the bike whole day long. Me and my friend returned from pindi the same day and when i came back i made my mind to get my bike tuned and also changed the (timic chain,got and air filter) ....plus 0.75ltr Zic engine oil and some little works now the bike produces awesome sound it feels like its a new engine.That sound "shur shur " was due to worn out timic chain.. The cost incurred for all this work was about 1200 including labour etc

    Thanks friends for ur great response sorry cant upload video of sound of engine coz i feel it would not be heard as clear as we hear in real with our ears on the spot
