atifnaeemmalik brother enjoy the bike on stock settings as brother asim said most most mechanics are idiots and let me tell you its not necessary at all to get the bike tuned at 1000km you can easily take it to 3000km if not than least enjoy it till 2000km after running check the full performance of bike.
if tappets are making noise you should not be worry about that as loose tappets are better you will feel less vibrations and good performance from bike feel light and most important longer tappet life
and there is no need to get your filter cleaned at 1000km also
The Less You Visit Mechanics Most You Will Enjoy Your Bike
Shafiq you went for tuning??? try some other pump
