My first thought at the mention of "chuffing" was of a spark plug that was slightly loose, but if you've serviced it, then that should have dealt with it.
not experienced much else for this other than with an exhaust - loose clamping bolt (eith at the cyl head, or another joint) or even a small hole in one of the pipes.
