I believe you NMK. Seemed a bit far fetched to say that there is no effect on the clutch from dust in the 2019's. My intention is to take a look and filter where I can without going to the extreme, because around here rides are not overly dusty. Our rides, so far, have been slow and over rocky roads. Some dust, of course, but not like some pictures I've seen. With that said, we will be in the S.W. (Yuma) this winter for a couple of months and I'll probably fine out a little more about real dust.
