Finally got my 04 wr 450 running great and went for a ride yesterday. About 4 miles into the ride we stopped and I noticed fuel leaking out of the overflow hose from the bowl on the carb. I shut off the petcock, cracked the gas tank and it was like opening a bottle of soda. Gas poured out and and after a few attempts I was finally able to open the tank. The fuel was bubbling alot so I lefft the tank open while I took off the vent hose to the tank and blew through it. No obstructions. Blew through the gas cap and still no obstructions. Put the cap back on and turned the fuel back on. I continued to ride and after another 8 miles noticed the fuel was leaking out of not only the bowl tube but all of them. Turned the fuel off and the leaking stopped. The only thing I can think of would be the float needle and possibly the o- ring underneath the brass fitting in the needle port or possibly a float level problem/ stuck float. I have not taken the carb apart yet to check it out. Anyone have any ideas as to whats going wrong and how to fix it?
