Question about KTM 125 EXC Motorcycles
Give the bike a proper service and check the coils. The service should include oil and air filters and replacing the oil and spark plug. 125 cc motorbikes tend to have a very hard life, they are generally abused by novices and not looked after, this will cause reliability problems. But, a good service will mean you have a standard from which to work, also you will get to know your machine and find where it is likely to go wrong in the future before it actually does.

If you get the sevice manual or contact a dealer to get the correct oil amount for your bike, they need to know the model and year, you have to have the forks off the bike. take the fork caps off, take the springs out compress the upper fork tube all the way and add the specified oil. if they also give you the measured amount from the top that's the best way to get both fork oil levels exact. there is a special tool that you set the oil level in millimeters and it sucks out the oil to the right level, but before you do that step after adding the oil always pull and push on the cartage rod several times to remove air from the cartage tube. you will hear the air coming out and you will feel the changes in the cartage rod as the cartage tube fills up with oil and the air is removed.
something i'm confussed on though is if you replaced a seal you would have had to brake down the fork to replace it. you would have poored the oil into a container, cleaned all the internal parts,and used a fork seal driver to install the new seal. part of your question asks where do i put the oil in? thats in the open end of the fork after you have taken off the fork cap. It sounds to me like you only replaced the dust seal on one fork. that is not going to fix your leaking fork. you need to replace the oil seal thats pressed inside of the top fork tube.

SOURCE: ktm output shaft oil seal
if you are lucky there is a clip behind the front sprocket remove both then pop the seal out drain gear box oil first though. if not which i think is most probable the engine will need splitting if you are good with spanners it is quite easy being a 2 stroke .in brief remove engine remove bore and carb in one lump remove sprocket gear lever split g-box .seal up push old seal out, from outside in, fit new then reverse prosses. a good manual will help.
