the bike wouldnt idle so i removed carb and cleaned out the idle jet.it started but didnt run properly and still wouldnt hold a idle..pulled the plug , while cranking i get one spark,then nothing.bad coil?stator?how do you check?

 

try a new spark plug

 

brand new plug.one spark first time its cranked over then nothing

Get stator wiring resistance specs,if trigger and charge coil check out,then possible cdi bad. Wouldnt hurt to check plug cap resistance(5000 ohm cap) plus check coil wire for bare spots. IF it was an old Honda I would say CDI because this is usually what they did! One spark only! BUT since its a Polaris,cant rule out stator,can do same thing!

 

IS THERE A SERVICE MANUAL I CAN BUY TO GET THE SPECS?

 

I have the manual for the 325 Trail Boss. They have a meeting starting now, but in about 15 minutes I can try to post the Troubleshooting page, and the page for the stator resistance test.

 

OK, had to do this in a hurry, so I apologize about the two pages being scanned together.

Hopefully, this will help.

Troubleshoot and stator resistance

 

the manual helped , thanks..but now it wont stop with the keyor kill switch.i disconected the black wire from the cdi unit,bike starts but doesnt turn off untill the black wire is reconnected..i took apart ignition switch and kill switch didnt see anything mechanicly wrong..is there a resistance test i can do to see if there good?

Just a thought, but does the 325 have a ETC (Electronic Throttle Control) ? If the throttle cable tension get to slack the ETC contacts close and grounds out the CDI unit and disables the ignition system.

A sign of the ETC out of adjustment is a slow idle until it stalls. If the ATV does not run with the throttle held open abit than its not the problem.

 

ILL CHECK FOR SLACK,THAT SOUNDS LOGICLE SINCE THE BIKE RAN WHEN I PARKED IT.THEN WOULDNT START,SO I REMOVED CARB AND CLEANED JETS OUT.THEN MY SPARK PROBLEMS STARTED..LETS HOPE YOU SOLVED THE MISTERY..THANKS
