Ran good and suddenly quit will start sometimes-- it's not carb as I have no spark!! I need some info on how to test cdi-- stator-- and so on.. Any help would greatly be appreciated !! Thanks in advance.

 

1st thing 1st, change the spark plug, then you'll need to check the trigger and stator magnet. but let's get the easy stuff out of the way first. put in an NGK spark plug and see what happens.

 

. I installed a new plug" champion" and it still won't spark.. Should I get an ngk even though this is the second new plug I've installed??

 

no, tell ya what, look at the kill wire coming off of the CDI and then check out the red slider kill switch on the left handlebar.

 

Ok I believe this quad has two cdi boxes..?? Can you show me a diagram of these and which is the ground?? I unhooked the plug for the handle bar switch I believe is the correct wires for switch and no change.. Thanks for any help in advance!!

 

let me go out there to mine and look it over.
