I just got a WB stainless steel headpipe from Nathan Woods (the #5 nationally ranked 4-stroke MXer who rides a YZ426F). Nathan cleaned house last weekend at the 4 stroke nationals event here in Spokane, WA. However, the stainless headpipe from his practice bike recently took a hard spanking, and now sports about a 1" diameter, 1/2" deep oval-shaped dent right on the front surface of the 180 degree bend. I took it to a metal fab shop here, they said that because its stainless I'm out of luck. I then called the "guaranteed 35 dollar pipe repair" guys from the ad in Dirt Bike, and they told me the same thing. Does anyone have any suggestions? I've thought of drilling a couple of holes in the dent, then maybe using a stainless steel screw and a body shop slide hammer to pull the dent out. Would it help to heat the pipe first before trying to pull the dent? I hope someone else has maybe successfully dealt with this problem. Thanks in advance for your input!
