Bought an old 2002 700 Sportsman that ran and drove good. Owner said he'd done the Polaris ignition system upgrade from the old Ducati system to the Kokosan. It had a small coolant leak between the case and inner stator cover. Nothing too bad, just a torn gasket . I'd guess he torn it while doing the upgrade due to removing too many bolts. It appeared to me that the upgrade was done as he said it was, the flywheel had the spaced magnets that look like the ones I'd seen in a You Tube video about the Polaris ignition kit installation. The only thing I noticed was the magnetic pick up coil by the flywheel had a little crack in the body of it. Stator and all wiring looked almost brand new. Up front, under the cover, the CDI box and coil are seperate parts. The cdi has a part number on it, but it's faded and I can't make it out. It ran perfectly until today. Started it to let it warm up before driving it, and in 3 minutes or so, it died. It'll crank, but no start. Doesn't even act like it wants to. Its getting fuel. Doesn't seem to be getting any spark. I pulled a plug wire and had no spark to confirm my thoughts. Lights and gauge cluster work fine. Where would be a good place to start looking?
