So I bought a 96 Polaris xplorer 300 4x4 2 stroke. It runs and drives but dies. Bought it from a family friend who I watched replace the carb, stator, ignition coil, rectifier, and pick up coil. Was still loosing spark could run anywhere from 20 seconds to 5 minutes. I bought it replaced the cdi box thinking that was it, changed nothing. Tried the original ignition coil and spark plug wire, changed nothing. I don't get it. I even added a ground changed nothing. I do have a spark tester light and shines bright then it goes out and machine dies. I'm lost and about to bring it to a shop unless anybody has any suggestions. Greatly appreciated for any advice.

 

Maybe ignition switch or handlebar on off switch issue?

 

I ordered both will let you know if that works when I get em on

 

Replacing both switches as in key and hand on/off cluster with the over ride and start button and lights did not fix the spark problem. Ordered another pulse coil to see if the one I have is defective. Should be in tomorrow will replace tomorrow night. Will update

 

Well that sucks, wish I could be of more help Not sure on your model but on some models safety switch in throttle ETC switch supposed to have just under 1/8 space between contacts some have said while idling contacts slowly close and kill bike don't know if that model has it or if it could cause what you are experiencing GOOD LUCK
