Replaced my spark plugs and changed my coolant yesterday! Spark plugs were easy and I can definitely notice a slight quickening of the revs. Changing the coolant on the other hand was an absolute pig... To get access to the radiator filler cap I had to remove the entire front end! That's right, all the front fairing! Ridiculous... Still, all done now. Next up, the TPS adjustment. Should get rid of some of the jerkiness at low revs.
