86 250r fork cap

[85 250sx]

well i noticed there was oil on my pipe the other day and after i looked closer i saw that it was comming from the top of my right fork. so i took the black plastic cap off and saw that oil is coming out of the little air valve on the fork cap. if i sit on the trike all the air in the fork just comes out and back in when i get off.
is there any way to fix this or do i need a whole new fork cap?

There should be a valve core in the fork cap. If there is, tighten it or put a new one in and you should be good to go.
