Hey Guys, I have a 2005 KFX 400 and will not cold start. I can roll it off and allow it to warm, then and only then will it restart with no problem. If it cools off, it goes back to not starting. I had the same issue last spring and had the valves adjusted in May. Fixed the problem. I have since ridden it about 5-6 times and is now doing it again. So I have 2 questions: Is it possible to need the valves adjusted again after such a short time? If not, is there anything else you guys can think of being the problem? Thanks for your help. Don

 

Anybody????????????

 

Hard starting is one of the problems that can be caused by tight valves.
