I let my cousin ride my moped the other day but she panicked and hit the gas and hit a tree. (To make a long story short) The 'ped is fine except for one little thing. The pedals seem to have turned..so they are both up or down at the same time. On the left side..the pin that holds the pedal to the pedal arm has popped out a bit..I cant figure out how to remove it. Can anyone help please??
