I just bought a 1991 yamaha fzr 600r and the previous owner said that the stator needed replaced and that's why it wouldn't start . I went to order the part and the parts store said he doesn't think it's the stator so I took the old stator home and put it back in and fooled with the bike for a little while . The battery was dead because the bike been sitting for a year , so I put my jump start kit on it and kept trying to start it and finally I got it to start once . It ran for about 45 seconds I then closed the choke and it cut off but wouldn't start again but it did back fire once and a small flame came out of the tail pipe . The previous owner said he had the spark plugs check the wires the coil and some other things with the carburetor and they all checked out good so I'm lost and don't know what to do . This is my first bike and I don't have a clue of what to do next , could u please help me I just want to ride !
