Found the same with a 2015 Australian restricted model - not much available over 110k and give up at 120k. Not good enough to tour in Australia. I tried sealing the holes in the throttle slide but no matter what I used, it simply fell out after a few weeks! So used the throttle side from a Harley Sportster ($88Aus from local HD Dealer), suggest a staintune muffler or similar (also much lighter), remove the mesh and snorkel in the airbox, change the main jet to a 146 or 147 up from 145 standard (I used Dyno-Jet Jet Kit from USA - about $50Aus), try An Eagle Mike KLX type needle (I used 2nd step up) remove cap from idle jet adjuster and start at 2 turns down).
All this changed the bike significantly. On my local test road, in 4th gear from 60k up hill about 300m - before it would do 100k at the top of the hill (telegraph pole to mark), after 125 - 130k consistently. That is about 60% increase in acceleration! Similar mods on dyno tune graphs you can find on the web suggest about 33 - 35hp at the back wheel. Standard Australian spec bikes give a whole 22hp at the back wheel - again about a 60% increase. Bike now cruises at 130k easily (in Northern Territory of course!) and will run up to 145k loaded sitting up (since tank bag fitted) readily to pass road trains etc. Not much left after that but the mods changed the bike from a slow but steady performer to one with entirely adequate performance - and much safer as overtaking times are much shorter - more fun too. Fuel consumption is essentially unchanged.
So - get to it, make the mods and enjoy!
