I live about a mile from the university I go to. I recently bought a 100cc dirtbike and was wondering if it was legal to ride it to school. I know I can't ride it on the side walk but what about the bike lane or street?
I'd check something in the fuel system it sounds to me like your not getting enough fuel into the motor. Check the filter to make sure its clear and check the pump. If both are fine and it only starts with starter fluid it mean that it has low compression which is a sign of motor damage.
