hello i have a 02 ninja 250 and it doesn't have a liquid/vapor seperator, is that ok or dangerous without one?
What does it actully do? i tried to find out but i don't really know what it does.

So on the tank their's three tubes, i'm only using two of the times but not the third one, which connects to the liquid/vapor thing, i brought the bike like that, then i compared to my friends bike and it was missing that piece. It runs fine, but will i eventually need to get one? Thanks.

pics or link reference to what you are asking about?

You're in Cali. Is that one of those obsessive emissions things?

If it is anything like a vapor cannister in a car, it pulls gas vapors from the tank....filters the water out....and purges vapor fuel back into the intake manifold.

I had one on my 1989 Mustang GT. Took it off and noticed absolutely zero performance issues. I believe it is just an EPA thing.....I am not sure of its necessity.

looks like i'm missing #4/#5

I knew it! Crazy emissions crap! Boo on California! :p

PM Vex. He has removed those emissions control pieces and can tell you how to route which hoses where and to put a one way filter on one of those vent lines as a precaution.

you can run w/o them, but if Cali ever starts emissions control testing, you will need to put them back on. I wouldn't expect that to happen, though.... but you never know.

ok, if only the emission then i'll just leave it alone. It runs fine with out it, plus i have muzzy so it seems to be a lil faster then my friends bike w/o the emission stuff.
