Easy enough.
Let bike cool overnight.
Remove left and right fairing sides and belly pan.
Remove filler cap to the right of the gas tank.
Remove the drain bolt from the steel tube that goes into the water pump.
Panic, rush around to find something to catch the coolant gushing out of the bike.
Once drained, refit drain plug, fill system with green/blue coolant mix remembering to burp the hoses.
Refit coolant filler cap.
Open the bleed nipple on the thermostat housing until coolant comes out, then close again.
Unscrew the water pump bleed bolt until coolant comes out, then close again.
Start motor and let idle for 5 mins.
Bleed both thermostat and water pump again.
Top off coolant.
Refit fairing parts.
Clean up spilt coolant :D

sounds good... 3 corrections...

*the fuel tank bolts must be removed, to allow the tank to move rearward to access the filler neck/rad cap...
*the drainbolt can be removed without all the plastic parts being removed
*when doing the burp, from bothe the bottom at the water pump, and the top at the thermo housing, the radiator cap must not be installed, it must be off... to allow the system to freely burp....


pretty simple process...

burp and drain locations were noted here... just a day ago...
