When I first got my ST13,, I was tweaking the windshield position constantly. But once you figure out the best positions that work for you,, I found I was adjusting a lot less frequently. But every couple of days,,, I run it all the way up and back down for cleaning. Especially in the spring,, when bugs are plentiful,, and seem eager to splatter themselves, even on the inside of the shield. I think I am putting more wear and tear on the mechanism for stationary cleaning now,, than I am from riding position adjustments. Since I have my tupperware off,,, I will do an inspection and lube this week,, Cat'
