Barsnake won't work with the buckhorns. Too many dents and bends in the bars.
As to the front wheel "binding", I have posted this so many times I feel like a broken record.....
Take your caliper off. Check it for debris, sludge, dust, etc. You could have a warped rotor, check for that using Greybeard's "pencil-style" dial indicator. But it is just as likely your front caliper needs a good douching.
The front caliper (both caliper's actually) is exposed to the elements and the world at large. Besides the build up of brake dust, I have found a small stone, a piece of twig, and the remnants of one of those large black and yellow bumblebees wedged in my front caliper. All of these things can cause the pads to remain in contact with the rotor, and that slight drag can cause vibrations. It don't take much to send a message up into the bars. Check it out and clean it up.
