I used to have a full poly windshield on my 800 S and it always seemed to be dirty and somewhat scratched up. So now I’m thinking of building my own frame and glass windshield and I’m undecided between a hand operated or motor operated wiper. I’d prefer the simplicity and easy install of the hand operated (not to mention the difference in price😕). For those that have the hand operated one how do you find it? Is it flimsy? Does it keep good enough pressure on the window?
