Darnell,
I just had all my clear plastic pieces "smoked out", but not with tint. What they do to get the smoked-out affect is to add a little black paint to the clear coat and can make it as light or dark as you want by the amount of black they add. They only need to paint the back side of the parts so they will be protected from rock chips. I just had my windshield, upper and lower wind deflectors, plus my front turn signals and rear brake lights smoked out for $125.....although that amount was factored into a larger paint job but I think it would be pretty normal.
Take your bike into a local autobody paint shop you should be able to get a fair price on getting them smoked.
