i dont have a deauville but i have a ntv 650 it has the same engine.
the engine has plenty of power to be fun if needed can cruise on the motorway easliy at speeds to see your licence gone i have gotten 230 miles out of a £20 tank.
i have not hurd of the header problem myself on the ntv's and i thought the deviles wear the same the headers are stainless as standard the problems are the collector box that rusts to high heaven but a arfter market pipe works fine to sort that.
my ntv is slightly different as it has a zx6r rear end on it lovely engine and bike but myself i am looking to upgrade to a sv very soon
