    2001 Yamaha GPR 1200 Weak Spark after 30Sec

    Hi guys My GPR 1200 starts and runs OK for about 10-30 seconds and then the spark on all 3 plugs gets weak to the point you can barley see the spark?

    Battery-good and is charging
    Replaced the CDI with used on of of Ebay...Made no difference
    The stator is my best guess now but every post I read on bad stators say they just quit not one story on weak spark?

    Has anyone else had weak spark after 10 seconds?
    Thanks
    Doug

    Stator and or rectifier, I would run it on the hose and do a battery voltage test and see if it drops in voltage.
