Hi guys I can never start my yz 250f 2003 and ideas on why or Andy tricks to getting it going
Have you tried a new plug?
Could be in order of likely. ...
Blocked pilot jet
Fuel screw adjusted wrong
O-ring dead on fuel screw
Choke plunger jammed
Hot start plunger jammed
Dead ignition/ bad stator
Have you checked valve clearances they get hard to start when clearances close up also test stator for a fault
start with the basics : fuel? Spark? Compression?
When did it run last?
