It’s been a tad over 7,000km since my last oil change. And of late, I’ve noticed that gear changing on the 400X seem to have gotten a little clunkier. Definitely not as smooth as I once remembered it to be. And so there I was contemplating the decision as to whether I should pamper my machine with some fresh engine oil.
But then, this clunky gearshift appears to be rather random too – sometimes shifting from one gear to the next feels like the gearbox of an agricultural tractor; but on other occasions, it could feel as smooth as a well-oiled precision machinery. And so I figured that it shouldn’t be the case of the engine oil approaching end of life.
