kawasaki ninja ex250 leaks gas into fuel filter and others?

i'm a beginer when it comes to motorcycle, i have done some work, but my motorcycle seams to have gas problems, when ever i leave the gas cock on to get gas running into the carb for too long, it will start to run into the fuel filter and longer after that. i think the float should stop so much gas from comming into the carb, could it be that the float is not stopping incomming gas? help>.

Thats whats they call it a"Kawasucky"

Noobguy, it's possible that you do have a bad float but more than likely it's a bad needle and seat that's not shutting off the fuel flow. They are inexpensive, so you might just go ahead and replace them and check your floats at the same time. Also buy a good manual.

wow you figured that out all by yourself, well your needle's and seat's are bad fer starters, I just want to know why. but don't really want to see what's in your float bowls,unless of course your planing on paying.... sorry Im dickin with a yamahaha carb right now that has stuff growing in there that no carb cleaner known to man will get out, dudes buyin a carb he just dont know it yet, so Im kinda in a mood!!!
