I have a 97 warrior and after it gets hot it don't want to start. This is something that has just started and it does have the dyna cdi on it...(hope thats not the problem) but I'm leaning more toward the plug. what do you guys think. I was going to pull it out and check it but I had a crash at the end of the day and I been to banged up to check it out.

 

I doubt it's the spark plug, i never had a 4 stroke give me problems related to the spark plug. But it could be the jetting, and to check the jetting the best way is to pull the plug and check the color of the ceramic part on the firing end. Being too rich could cause it to start hard when it's already hot.
