fixing a bent header?
Posted May 07, 2001 - 12:25 PM
I creased my header about 1 month ago due to a crash, and I am wondering if anyone has tried to bend theirs back to normal? My header is a White Bros high boy stainless! It is creased right underneath the radiator (about 2-3 inches from the exhaust port)!
I was thinking about cutting the header right in the middle where the crease is, then re bend it back to a circular shape, and then reweld the 2 pieces back together? Would this work w/o exhaust leaking? Have any of you guys done this?
It seems like every time I have a "pretty good crash" the header always creases in the same spot! Have you noticed this too? I am getting tired of buying new headers, since the companies "hose" you for $150 for each one (which is highly overpriced...they cant be as hard to produce as 2 stroke pipes, I mean come on) I would appreciate any comments you guys have! Thanks,
I get my kicks on a 2001' YZ426!

Depending on how bad the crease is, we sometimes block off both ends of the pipe make sure its an air tight seal ( usually by brazing plates at each end ) the we fit a steel tubeless tyre valve in the plate at the furthest end from the crease. then we pump air into the sealed pipe while heating the creased area. Be very carefull not to apply heat in a small area as this can blow a hole in the pipe. Also don't use too much pressure 5-10 psi should be enough depending on the wall thickness
Good Luck !
