Front rim flipping help!

[EX_stunter]

I want to flip the rims on my 250ex. I tool the rims and tires off and put them on backwards. Than noticed that the valve stem would hit my diskbrake! making it impossible to ride w/o breakage. any help?:mad:

Take the tire off and cut the old valve stem off....Measure the hole and redrill a new hole that size on the side you want it on...(opposite side of what you had) Install a new valve stem in the new hole....Put another valve stem in the old hole to plug it but put it in backwards....Stem pointing inside the tire...Put tire back on and pump-er-up and go...I did it and it worked perfectly....;)
