Hey guys had some questions for ya about the wr426f. I recently purchased an 01 wr426f. looking to get the most power out of this bike. I had a 05 wr450f deristricted that was an absolute blast to ride. With that said I like my new to me 426 a lot. Smooth shifting, linear power band, but would like some more umph. it currently has a yz426 pipe on it. what mods will really bring it alive? I was thinking over the winter to do a yz450 exhaust cam, was contemplating getting a yz426 aftermarket pipe (i.e. fmf or a t-4) not sure how much more power that would be than the current yz pipe on the bike. Anything else to help bring this bike to life? And honestly will it ever have the power the 450 had? Thanks for your input guys.
