I bought the first calsci windshield a little less than a year ago. When I bought it, it had glowing reviews for both performance and durability on an RT (IIRC, I saw some positive comments you had written about it, Steve). When I sent Mark the note about the windshield cracking, he had a new windshield coming immediately, no questions. Great customer service, but he didn't seem surprised by the problem. I did a web search recently and found where there were some others that were also having the same problem.
When I compare the calsci windshield to the CB or the stock screen, I notice two things.
a) The drill through on the calsci is much rougher and less polished than the other windshields, particularly the counter sink on the surfaces.
b) The two center holes are closer to the center line of the bike than on the other windshields. That results in the screw standoff on the windshield mount for the center screw pressing very tightly against the outer edges of the center windshield mounting hole.
I wonder if calsci isn't having quality control issues with the recent RT windshelds (maybe other models as well). The three things that come to mind for me are:
1) They changed vendors for the plastic and the new plastic is somehow more brittle.
2) They changed the vendors that are drilling the windshields and the pattern being used is enough different to create a problem.
3) They either changed tooling or are using old tooling that creates a problem cutting that center hole.
The other obvious possibility is that I screwed up the installation. Initially, I was open to that possibility, but it's happened on three different calsci screens. I've had the stock windshield on and off several times with no problem and I haven't had any problem with the CB windshield I used to replace the calsci. If it was an install issue, why no problem with the other brands?
