I MADE A TRADE FOR THIS BIKE. THE OWNER TOLD ME IT HAD NO SPARK COLD BUT IT WOULD PULL START. I BOUGHT THE SERVICE MANUEL SO THAT I COULD TEST IT PROPER. THE STATOR FAILED THE RESISTANCE TEST, SO I FOUND A USED ONE FOR THAT TESTED GOOD.THAT DIDN'T WORK SO I REPLACED THE CDI WITH A KNOWN GOOD ONE. TO MAKE A LONG STORY SHORT, I HAVE REPLACED THE STATOR AGAIN, THE CDI AGAIN, THE PICK UP COIL TWICE, THE IGNITION COIL AND PLUG WIRE. THE SECOND STATOR EVEN CAME COMPLETE WITH THE WIRING HARNESS.I HAVE REPLACED THE ENTIRE SYSTEM WITH NEW OR KNOWN GOOD PARTS OFF RUNNING BIKES. AND NO THE KILL SWITCH IS NOT GROUNDED AND THE FLYWHEEL SPINS. WHAT SHOULD I DO NOW?
Hi and welcome to FixYa,
Initially, test for the presence / absence of below described voltages using an analog / needle type voltmeter when starting the bike:
Good luck and thank you for asking FixYa.
If The Guy You Bought The Bike From Said It Would Crank Push Starting. But Wont Crank With Kick Starter. That's An Indication Of A Broken Reed. Hi-Revving 2- Strokes Eat Old Reeds Quickly. Replace Them With Carbon Fiber Reeds If Possible.
I Have Several Solutions Posted Elsewhere That Explains How The Electrical Systems (CDI) Work. The Stator Via Rotating Magnet (FLYWHEEL) Generates A.C. Current To Capacitor After Being Rectified To D.C. Current Internally By The CDI Module. This Current Is Stored In The Capacitor Until The Pick-Up Coil Triggers This Current To Discharge To The Primary Terminal At The Coil. Secondary Side (PLUG WIRE) Fires The Plug. Also Be Sure The Plug Boot Is Threaded Into Plug Wire(GOOD CONNECTION). See My Other Postings For Testing Procedures And Cautions
