Dear Athar25,
bro if the oil level is low thats not good for the machine.
how bad it is depends on how low the oil level is.
you can do 2 things now.
(H)1 you can have the oil changed riteaway.
it dosent mater if you do it now or @ 250-300 Km's.
if you can afford it get it changed now then get it changed again in 500 Km's after the first oil change and then carry on with regular oil changes as per oil cycle recomended.
(H)2 if you just got your bike and havent riden it much n the oil in it is of good quality and you think your comfortable with it then get a new oil can and add oil to the existing oil untill it reaches satisfactory level.
you can youse the rest of the oil some time later.
