    its normal.....infact its sign of good engine.....its due to engine parts contracting due to cooling after engine is turned off.

    when sludge is build up in engine specially in valvetrain area then this sound rarely comes .......this tuk tuk sound comes from valve train region ..........when sludge is build up then contraction is not so rapid as sludge has covered it so then it doesnt come......the main cause for it is the two different types of metals in the rocker arm.....one is copper which is tappet part which strike valve stem other is iron body of rocker arm.....they contract at different rates so when they contract rapidly this sound come......but when they contract gradually due to sludge then this sound dont come.....if u want to observe it urself then when engine is hot open valve cover and pour 4 5 drops of engine oil on valve train......u will notice this sound..........try to remember action of bimetallic strip studied in primary grade science......same sound comes in it also.....when u heat it up and rapidly cool it by pouring water.....in engine case there is no water instead its oil which has accumulated in valve train.hope u understand.so in short a clean engine produce that sound more often.

    good. the answer is convincing but its a sign of a clean engine not a strong engine. ho sakta hai banda oil time pe change krta ho but ultimately riding rough krta ho.
