You guys who are owners of 400's, what should I do straight up, what are the problems, and about swithching wheels around. I would do that but it involves drilling and that scares me. If it is just for the valve, then that is fine. thanks in advance.[img]i/expressions/face-icon-small-smile.gif[/img]

 

Take the wheels off and flip them then put the quad on a jack and turn the wheel. If the valve stem doesn't hit anything then its alright.

 

What do you mean, I understand the valve stem, but what could it hit, it is on the inside of the rim, yes?

 

The brake calipe or maybe the disc.....on some quads like I think the 250ex if you flip them they will hit something.
