paulospug Posted July 15, 2008 Share Posted July 15, 2008 Hi. I have recently bought a YZ250 2000. The bike was running before it was put into a garage for 3 months, but no longer sparks! There is a very low voltage coming to the cdi unit (approx 0.6v sometimes.... i think) from the magneto, but nothing coming to the plug. I have put another 2nd hand coil and cdi unit but still no joy. I am about to kick it and cry Can anyone offer any advice? I have had the flywheel cover off and cleaned it up but now have run out of things to try...... HELP! Thanks, Paul Link to comment Share on other sites More sharing options...

Thanks, Paul Check the battery condition (charge & check the plates ain't warped) then the connector at the regulator/rectifier. Sometimes when you rest a bike for a few months you get a build up of verdigree (green powdery crap) in the electrical connections, this can cause the drop in voltage.
