i have a 04 250 ninja and am stuntin it. i have a major problem with the crank case vent leaking into the air box, when it gets to 11-12 o'clock. if anyone has any ideas on how to fix this that would be great.

 

does it cause it to smoke severely when it leaks into the airbox?

 

hahahah awesome buddy, glad to hear more people stunting the ex250. I love mine, you have to clutch it right to the balance point because its so gutless.

I took off the main vent hose (the one sorta above the transmission- like to the rear part of the motor) and I ran it to the front of the bike and into a gatorage bottle. I punched some holes in the gatorade bottle so it would vent but not leak. Once a night, Id empty it back into the crankcase. If you overfill the oil it will pump out a lot more.

I think the correct way to fix it, is to drill a hole in the top CENTER of the valve cover, and lead that to a vent. (if you drill in the side of the valve cover it will leak out when you do turns- I learned that the hard way)

good luck.

 

stuntin the ex250 yeah

 

no martino i myself do not have to clutch it up to balance point b/c i made a 60 tooth sprocket for it. and yeah i tried the bottle thing and that seems kinda shady. i think ill do the valve cover thing. seems like it would work 10x better. thanks for the help.

 

did that drilling the hole on the top of the valve cover really work?

 

I think the ex250 is a god-ugly looking bike.

 

i think ur endo is garbage. the 250 is a champ

 

^ i like this kid... good to see someone stunting a 250 that doesn't stare into the cam during power wheelies, keep it up dog

 

he probably fell right after that pic was taken too. LOL

 

haha, good job killing the 250.

 

Sorry plhusaf, didn't mean to offend you.

I was saying my opinion on how it LOOKS, not on how much SKILLS you have stunting it!
