Cut 2 inches off my shield an had it tinted 2years ago no problems as off now. Make sure there are no scratches where you want the tint . Only cost me 5 bucks at the shop so even if it goes funny i will just have it removed an done again.
Mine is black & where my windshield bags rub it leaves a mark so I just shoot some black paint on it. I do have a clear one that I cut down & am thinking of going with window tint & put some flames in it.
Memphis shades sells windshields that are tinted for a reasonable price. I picked one up at the local HD shop on the for sale table after military discounts only paid 32 bucks. Looks great on bike goes from clear on top to black on lower half.
