I've actually seen this fix this particular issue in a number of cases.

Here is my crazy routine with my GSXR. Works like a charm. If I dont do all this , they will drag.

1. spray the calipers with brake cleaner and clean the pistons
2. carefully use a flat head and push the piston and pads in
3. loosen axle nut
3. loosen pinch bolts
4. bounce on the front end
5. reinstall the calipers
6. tighten left side pinch bolts
7. tighten axle nut
8. tighten right side pinch bolts
9. SLOWLY pump the brake lever and I mean SLOWLY until you have good pressure
10. put it on the front stand
11. spin the front wheel and hit the front brakes several times to kind of jar line everything up.

This should fix it. I also have my pad springs / clips / anti rattle whatever you call ems out.... GL!

You you did maybe you didn't align the guides right and it's applying pressure to the piston on the MC which is causing both calipers to squeeze more on the brakes.

Try remove some fluid like Patrick said and see if that helps. You can also try removing right caliper off and see if the left caliper works as it should by spinning the wheel and and pressing on the brakes. Then vice versa.

I've seen rubber brake lines collapse on trucks but never seen it on a bike so I doubt that's your case.

edit: I'm no mechanic... just throwing out some plausible ideas.
It's near impossible to put the spacer in backwards on the gsxr. The front axle wont push through if you have it on wrong. Ask me how I know lol

So I did the step by and it seemed like it helped a bit. I did it first without the springs and backplates and it worked well, I put the plates and springs back in and it drags a bit more but still not like before. I'm getting @ 1.5 rotation spinning the wheel. Gonna go for a ride tomorrow eve if the weather holds up and see how it goes.

No Clue,
How freely should the wheel spin?
Why not go to a bike shop and see what a new bike does.
maybe this is a non issue.
If the drag is not to the point of building up ecessive heat I'd be inclinded let it go and just and check every couple of days to be sure it is not getting worse also check every couple of hundred miles that the pads are wearing evenly etc.

I had that problem when I changed my pads to EBC. I just had to ride hard, and break them in. It took about 500 miles, but no more dragg.

I bet your MC has something to do with it as well. When I changed to the r6 MC I did not have to go through that hassle. I don;t even have to push the pads apart anymore and front wheel swaps are a breeze now. I still tighten everything on the the ground though.

its not unusual for gixxers to drag like that. mine has been like that for years. helps a little to remove the pistons and lube with SilGlyde but will never really go away. I know it seems up but doesn't appear to hurt anything - although you probably won't set any mph records at the track.

My rear piston was doing pretty much the same, I did what Cdil did, but cleaned the caliper pistons with simple green instead.
