Hey, I am new. I view a 420 rancher 4X2 2011. For two years the tv has a problem when I use it for approx. 2 h. The engine heats up and the ATV star loosing power. Like drowning and I have to turn it off and wait 10 minutes and then it starts working correctly. What is rare is that it doesn t turn on the light of temperature. Someone told me that it could be the CDI. I don't know what is that. They said is something that has to do with the spark plug. The technicians can't find the problem. Do you know about this?
