Trying to help a friend with his 2004 Yamaha warrior 350... It wasn’t getting a spark so we replaced the spark plug, cdi box and coil. Have tested the kill switch, checked fuse, everything is good there. Monday (8-20-18) we installed a new stator and got spark, ran it around my trails for about half hour then put it up. Today (8-25-18) we went to go riding and it wouldn’t start, again getting no spark... can’t wrap our heads around what happened when we got spark back then a few days later nothing... any help would be greatly appreciated
