Ok so I was cleanin her up today and decided to ride the trails a couple times after i did. And when i was riding, i noticed that when i push the throttle right past idling point, it bogs out on me. everytime i would be foolin around in 1st gear everytime i gave her a tad bit of throttle she would bog out on me. but any other times its fine. doesnt happen in any other gear. only happpens when i rev it just past idling point. i cant identify the problem. anyone know what it is?
