    250exc fuel problems

    PACKING HAS BEEN CHANGED RUNNING PLUG THAT IT CALLS FOR AND THE 02 HAS THE SAME PLUG. I DID CONFIRM THE JETTING IS FACTORY BY THE FACTORY BOOK. I HAVE NOT CHECKED THE JETTING IN THE OTHER BIKE YET.

    250exc fuel problems

    I have a 2000 250exc brand new rebuild 4 hours on it. Before the rebuild it used about a half more gallon of fuel and sprays oil all over my clothes while riding. my 2002 250exc does not do that. I rebuilt the entire engine and its even using more fuel and and still sprays oil out the pipe and all move me and my fender. While its running you can see the fuel/oil moving around at the end of pipe. The carb has factory jetting and settings and i run the bike at 44:1 with amsoil interceptor oil. (also did this with klutz) I ride the bike on the road, pavement but a lot of dirt roads also. My buddy has a 08 250xc 2 stroke and you can stick your finger down is pipe and not touch oil or fuel. Any input would be great
