Question about 2004 Yamaha YZ 450 F
When I turn the fuel on a stream of fuel runs out onto the ground through the Caburetor. The bike runs good and seems to operate well, its just when I turn the fuel on it runs through the system onto the ground. I can turn the fuel off and it will run the Carburetor out of fuel untill I turn the fuel back on. Is there a valve that is broken of stuck in the Carburetor?
All u got to do is clean the carb and if u find anything broken or worn, replace it. inside the carb theres a little cylinder were the small needle shape piece of metal connected to the floats,it goes up and down in the little cylinder and can possibly have some dirt, sand, grit lodged in there. if u have a manual thats fine, if not, u can be like me and use common sense cause u have to carefully unconnect all the wires connecting to the carb, then get a smaller size screw driver and unscrew the 4 screws connecting the float bowl to the carb, then turn the carb upside down and slowly watch 4 a little white piece of plastic, roughtly a 1 square piece, all it does is help prevent the gas in the bowl from slosthing around, i mean i lost it a million times and it did affect ****. only the best **** talkers and littles boys that think there the **** or RC4 will need that piece. but back to it, just carefully remove the float then unscrew the floats and clean them. if u got a air compresser thats great cause u can blow the air out of the tight spots, u can grab one for 40-50 bucks. then unscrew the cap were the throttle cable enters the carb, pull it out and clean it. make sure to clean out the entire float bowl. real quick u got to unscrew the accelerater pump cover and clean it out,oh and the little brass insert on the left side part of your carb if your looking at it from the back. thats your hot start. follow the hot start cable from the handle to the carb, then unscrew it if it is not already seized, u need to take it out and put a very small amount of grease on it. and remember if u get stuck just think of the situation and use mad common sense and youl be alrite. and since your asking a question that is easly fixed i no u aint a pro so just dont take anything off that i didnt tell u to and youl be just fine
