2004 TTR 225...Just bought it and it has been it storage for 5 years, basically a brand new bike. When I run the bike gas pours out of the hose which is connected to the bottom of the carb. I turn the petcock switch to "off" and the fuel eventually stops pouring out the hose. I disconnected the fuel line from the carb and opened the valve, gas pours out of it. Is there too much fuel getting to the carb?
