I think you might be able to fix this pretty easily, I'm hoping anyway.
You mentioned orange fluid? Your brake fluid should be almost clear. Probably you have dirty fluid, possibly from the right side bleeder valve being leaky. I would purge the fluid. It's an easy job. Get some small clear flex tubing at the hardware store. I think 1/4" or the next size smaller will do. If it's flexible, it will stretch over the nipple on the bleeder valve. Put your bike on the centerstand, and remove your MC cover. Wrap a rag around the handlebar to keep any spillage from splattering, and probably put a towell over your gas tank to keep the same from getting on your painted surfaces. Brake fluid can be pretty bad to paint in a short while!
Take a clear glass bottle or jar and put some brake fluid in it, enough to keep your tube submerged. You can tie a heavy bolt or nut on the end of the tube with a wire tie to help keep the end submerged. Fit the other end over your Left side bleeder valve nipple. (left as you sit on the bike), as this I believe is the longest side, and it helps to bleed the longest side first. It may not matter though. Make sure your MC is full of fluid to the top full line. During this process, make sure you have fluid in the MC and that it doesn't run dry, as it will introduce air into the lines and you have to start over.
Use a 10mm open end or box end wrench and put it on the bleed valve but don't loosen it yet. Squeeze the brake lever all the way in, slowly, so it doesn't spirt fluid up in the air. (The manual says to do this with the cap on the MC to keep dust and debris from getting in there, so use your own disgression here. If it's windy and dusty, maybe that's a good idea. If it's calm, leave it off so you can see what you are doing!) While the brake lever is compressed, hold it, and with the other hand, open the bleeder valve just enough for the compressed fluid to squirt out the tube, then tighten the bleeder valve, then let up on the brake lever. Repeat this process over and over, checking between times to make sure you are keeping the MC full of fluid and not letting air into the lines. Watch the tube and repeat this process until you see nothing but clear DOT4 brake fluid coming out of the tube, and no air bubbles. Once you have clear fluid and no bubbles, tighten the bleeder valve one last time and replace the rubber cap over the nipple. Put the tube over the nipple of the other bleeder valve and repeat the process, again until you see nothing but clear, non-bubbly fluid coming out. Tighten that bleeder valve one last time, replace the rubber cap and top off your master cyl and replace the cover. You should be done, and your brakes should apply evenly.
I feel like it is possible that your brakes were applying more to one side because of the bleeder valve being slightly open on the one side. Hopefully this will solve your problem. Good luck!
