my research has found problems with the 2011/2012 ducati ignition[made in india].in u.s.a. the wr 250/300 is not sold with lights fitted.i know of wr 300 owners in australia who have had erratic/no spark problems with wr300 2012 mods that may of caused multiple engine failures
did you make sure the new spark plug was igniting if it is or if its weak you might have broke the flywheel key was it running fine when last used there can be alot of things it could be 2 cycle engines must have 120psi of compression ,the right fuel mixture,good plug right gap between flywheel & magnito (spark plug wire connect to to get spark) and not rust on flywheel & magnito hope this helps let me know thanks
All wires on a small engine except for the spark plug wire are to ground out the spark and stop the engine. Except a few for accessories and on generator/welders.
Knowing that, there is a small main wire that comes from your coil and leads to all other wires. It usually sits under your gas tank and runs toward your on/off switch or ignition switch. To see if it is any off your shutdowns gone bad, disconnect this wire. If still no spark then you either have a open in this wire or your magnito (coil) is bad.
If it starts, then unplug all the wires going to the kill wire and hook them up one by one until you find the one that kills the engine. Follow the wire to it's source looking for breaks in the line. If no breaks then the switch is out of place or bad.
Note: check your oil level first. Most engines come with a low oil sensor that will kill the spark if the oil level gets too low.
To check is your magnito is bad or you have a short, disconnect the wire at the magnito found by the flywheel under the flywheel cover. Tuck this wire out of the way and try to start your unit. No spark then you have a bad magnito.
