My 06 YZ 125 Fell Over Last Weekend While I Was Gone. I Was Gone For Like 2Hrs And 30 minz. When I Got Back I Went In My BackYard And Picked It Up. I Tired To Start It And It Wouldnt Start. I Changed The Spark Plug And Cleaned The Airfilter. Does Anybody Know Why It Wont Start? Your Replyz Will Be Appreciated
