I rode with my windshield from the dealership to my house. Took it off and put it in my garage art collection.
No cracks yet!
Seriously, I did reinstall it on a cold day in December when I decided to ride in at 32 degrees on a Saturday. Yes, we do have a minor winter season in California. Anyway, I couldn't ride above 80 miles per hour as the damn thing would buffet so bad I thought my head would explode.
Again, I took it off and put it in my garage art collection.
I am now going to go old school windscreen on my 5k summer trip. Yep, sleeping bag bungeed to the handlebar to divert the air up.
I am going to upgrade the actual windscreen at some point, but I need to test ride some differing heights to see what I really need at 80+ and I am not done with my research. I think it is a fine line on the torque at the attachment points. Too tight and they crack. To loose and the rattle or vibrate....
