So after finding out that Wr450 exhaust cams(and other hot cams) have a auto-decomp lever that will fit into a 400/426f, I have decided to go that route rather than fighting with the decomp mechanism on my 426.I just want to kick and go, but it isn't that simple with the 400/426f. Especially in the woods. I have worn myself out to get the timing just right in soggy mud for it to start. So, most of you already know that this is my first dirty and thumper and would like to be able to really enjoy this bike. So if I go with the exhaust upgrade cam, might as well do the intake too, is there a down side to this swap? Pro's& Con's of riding it with Hotcams on these thumpers?
