you likely blew your oil seal..
BUT you might have just cought some dirt with it.
get a feeler gauge and pick the finest blade you have,
then carefully run that blade between the
tube and the oil seal at an angle that'd push all debris OUT of course..
all around.
That should clean all dust and sand out and reset the inner lip to seal against the tube (hopefully)
Now wipe your fork clean and observe..
If it wettens again from oil, you will need to replace it I'm afraid.
which in case of a motorcycle requires some special tools (long allan keys mostly)
and some serious force to pull the tubes apart.
IDK about a mini bike, but I hope it's easier let's say.
fork oil is available in every motorcycle shop,
(amount of oil is crucial.. so measure what you had in there to get an idea if you don't find the repair manual for the Baja)
seals can be found by their dimension and type (OD of inner tube[should be 1"], ID of outer and things like lip count, steel spring, dust cover etc)
A pic and it's dimensions and the motorcycle shop should be able to find you a replacement.
