i have a 2005 baja 90 quad that has a weak spark.its kinda white with an occasionl blue flicker.the plug is brand new but it still wont start.some one suggested replacing the stator but its kinda expensive.where should i start?

 

I see it's been a while since you post and you really got alot of help here

I currently am having the same problem. According to BAJA it is either the CDI, stator, or the coil. He told me the coil hardly goes bad. I have a new cdi at home that I aquired earlier(long story) I am going to try that and if it doesn't help, I'll purchase a stator.
Have you got yours fixed and if so what was the final solution.
