I have a honda 2003 cr125 dirt bike, flushed all fluids, changed out spark pluge, checked out the clutch, pushed bike down the street, jumped and the bike still does not to want to start up.
Can someone tell me what else should i be looking @? thanks.

Clean the carb.
Check for spark.
Check for fuel delivery to the plug.
Do a compression test.
Clean/replace air filter.
