Yep, it's a standard problem. From what Klockwerks said the problem was that the actual windshield mounting differed from the 3-D CAD file that Victory sent them. Mine cracked soon after I put it on as well and they replaced it. Like others have said you have to use a rubber washer on both sides of the windshield. Mine has now been free of cracks for quite some time now.
