Check www.racetech.com/. The offer calculators to swap springs and oil weight, or they have their Gold Valve Cartridge Emulator packages. Go to that site, click on Product Search, then select your model-year bike (though they're all the same fork from 2009 to 2017). When I was riding the hell out of mine, I'd always wanted to upgrade mine with the emulators. Never have though as my usage of the bike in the last 6 years just doesn't justify the expense right now.
As stated above...switch the internals. The cheapest way is to switch the oil. Going to a 10w or 15w oil will make a difference. I would start with some oil just to get a new feel. I had a blown fork seal so i replaced the seals and oil with 10w. Noticeable difference from stock. Next time I replace the seals I'll use 15w.
Just did gold valve emulators. Front definitely feels more planted. Fork removal and disassembly wasn't hard, just too some time to do it all. You need to drill 2 holes into your damper rods. Amazon was cheaper than the local bike shop. couple seals/dust cover, 20wt oil, and you're good to go. My weight didn't require replacement of springs.
I went with 20wt oil with no issues. Huge difference. Also added fork preload spacers. I'll be honest I dont know much about suspension but I made a mechanical engineer friend who helped me sort out the front and it made a huge difference.
Grain of salt I'm a heavy guy that looks like he should be on a harley so ymmv
