I have a 04 kfx 400 thats been driving me crazy lately.. ive owned the bike for a couple years and has never giving me any major problems.. now im stumped.. The quad starts up and runs fine for a couple minutes, (probably just enough time to get up to riding temperature) then it blows the main fuse thats under the seat and i lose all power, if i try to replace the fuse right away itll blow it instantly. When i wait for the bike to cool a little i can start it but when she warms up again it blows the fuse. Ive checked to the best of my knowledge for any shorts or breaks in any parts the harness but havent found anything out of the ordinary. Have any of u ever had any problems like this before? Btw thanks in advance.
