POPS TOOK HIS 2003 KFX400 OUT FOR A BLAST TODAY AND IT JUST STOPPED DEAD IN THE TRAILS. I THOUGHT IT WAS A PLUG BUT WHEN WE CHANGED IT THE OLD ONE LOOKED FINE. THE QUAD STARTED UP AND GOT ABOUT 5 MIN DOWN THE ROAD WHEN IT STOPPED AGAIN BUT THIS TIME WOULD NOT START ANYONE??????????????? COULD IT BE VALVE SHIM CHECK TIME???

Check and make sure the battery is fully charged, Sometimes it will have enough power to turn the starter, but not enough to get it to power the CDI to get the spark hot enough.. Happend to a buddy at the dunes a few weeks back.
