Not sure what the difference is, but the 86 one will bolt on the 85 engine, they both use the same gasket part number. The 85 and 86 carb part numbers changed, so that could be a potential issue if the size changed. 250r's are not my strong point though.
Which boot are you talking about here? The carburetor-to-reed valve isolator boot, or the airbox-to-carburetor boot? If it's the airbox-to-carburetor boot, it shouldn't matter which year, '85-86, that you use. If you're talking about the carburetor-to-reed valve isolator boot though, externally the 2 years are the same, but internally, I believe the '86 version was optimized (shaped differently) to flow better, with the '86 style reed valve stuffer. All of these parts will interchange between both years & carburetors, but the '86 style will flow better, when used with the '86 style reed valve stuffer.

I have used an 89 trx 250r intake boot on my 85 with both 85 and 86 carb plus a 38 mill works fine with all three carbs.
