I know its not a kdx but i just bought a 04 yz 250 so when i took it for a spin i noticed oil coming out the hose that runs from the kips box just wondering what may cause this never had one do it before

Kips on a YZ250? That's definitely the cause of the problem.......
However, it could be the anti-matter rotation correction device.

Hrmmmm..... This requires more thought.

Common thing on a YZ250. Power valve spooge, mine would spew out a few drops once in a while. Nasty gorp, but normal.

so you think its just nothing i know its now a kips but i figured it would better explain it but just got it today will ride more tomorrow to see if it does it again

Just to make sure you understand . . . KIPS is the powervalve for specific Kawasaki models - Kawasaki Integrated Powervalve System I think. Your's is also a powervalve it's just not named a KIPS.

It's a YIPS . . . nah, just joking! Don't know if it has a name.

I have a Suzuki RM250 and spooge comes out of the powervalve drain tubing same as yours, that's just the tubing doing the job.

It probably will. Mine alway liked to dump a small glop on the bed floor of the truck on the way home from the trail.
Great bike the YZ250, mine was just a little much for my skill level here in the woods.
A picture..

YPVS I like YIPS better
