I bought the scooter for $5 dollars at a garage sale and didn't notice that the alignment was off until after I got home. The razor scooter was still in decent condition, however the alignment between the wheel and the handlebar was terrible.
I simply took an allen wrench and loosed up the bearing. Then with the razor scooter flipped upside down, I stood on the handlebars and adjusted the wheel.
Make sure that you have a tight grip when adjusting and that you have an easy to use allen wrench.
