hello all, im new to the forums and had a question hoping someones knowledge could help me out a bit. i bought a 2001 400ex about a month ago and noticed when i got it that you could put the key in and turn it on and crank the quad and pull the key out of the ignition with it still in the on position and quad still running. that wasnt much of a problem at first, but now over the last week and a half sometimes when the quad is running and i turn the key off it will stay running. sometimes it will turn right off. and ive also noticed that after riding around for a while sometimes when i shift to neutral the light will not come on. has anyone experienced a problem like this before or know where to start on fixing this?
