    I cant read that. Did you say you took the carb off?? Of did u pull the fuel line and drain it.

    Sounds like your floats stuck. There is a float and needle inside the carb, When there is enough gas in the float bowl, the float rises sleaing the needle in the carb to stop fuel flow. If its stuck, fuel will continue to pour in, and out the overflow tubes.

    Or if you took the carb apart and you weren't carefull you could have messed up the float height.

    Could be some crud got between the float valve needle and it's seat, preventing the float valve from seating and sealing.

    Take the carb off, pull the float bowl off and take a look. Clean out any debris. Make sure the float level is right and the float moves freely.

    Re-assemble with care, put it back on the bike and see if it still leaks.

    I assure you its really not that hard. Just a couple bolts and its off. On my 00' CR, i remove the number plates, then loosen the airfilter box to carb clamp, and remove the 2 bottom bolts on the subframe (I only loosen the top), and just swing the subframe upsidedown. Then pull the carb off. The more I take off, the easier I find it to be.
