2008 YZ 450 Carburetor Leaking

3 posts in this topic

Hi guys, i've never had a problem with my bike/carb since i bought it in 08 but i went to start it up from a few months of not starting it and i have what seems to be the fuel coming from the seal of where the bowl meets the body of the carb. I stripped the carb cleaned it, put new gaskets in, but once put back together it still leaks. When you turn the fuel to "ON", gas leaks right where the hose attaches to the carb, i figured it might just be old and that little push pin for a clamp is worn, so i bought a screw clamp. It still leaks from it, also it pisses gas out of the bottom of the bowl, the little over flow line i think? So i'm not sure what to do, i'm not an expert at this, its obviously not that obvious but something is preventing it from holding fuel. 

 

Any suggestions?

 

Is there a carb fixing website? Do you suggest i just bring the carb to dealer?

 

Thanks!

The carb is flooding because the float and float needle are not shutting the gas off when it's full.  The float needle is worn or damaged, there's dirt in/on it, the float is binding on its pin, assembled wrong, or just set at the wrong float level.

Ah ok, i did replace the pin and the other needle as well when i did the gaskets. Ok, maybe i'll take it apart again and see whats up. Thanks for the suggestion!
