I have done something to the steering on my Blaster, When I drive straight, the handle bars are turned a little to the right. It doesn't look like there are any things broken or bent under it. Can you help me find out what it is. Is there any easy ways for me to fix it by myself.

 

If you are big enough to straddle one wheel and reach the bars, place your feet on either side of a wheel & holding the bars, give them a sharp tug in the direction you want to go to align them . If you can't do it then you'll have to find a place to block the wheels and try it there.

 

Piece of cake! Turn the handlebars straight, and then adjust the tie-rod ends so both wheels are facing forward.
