Avoid giving full throttle & if i was @ your place i would change again oil
2nd around 600km than on 1000km, later on after every 1000km
well now you may drive it little higher speed if you are ok driving around 40,50km/h
you should continue else you may give some throttle now drive it around 60km/h as its fairly run now
