How many kms on the odo??
A complete drain is required around 30-35,000kms. Also, my suggestion would be get it done at the SVC because it requires careful removal from the thermostat pin (a delicate part), the hose then comes loose. Do not fill direct coolant, some coolants require mixing of water.
Remove both side fairings, the side panel, one side will be the coolant container and the other side will be the coolant inlet cap. Unscrew and the chamber with hose comes loose.
My sincere suggestion is dont do it unless required or told by SVC, also get it done from them itself.


best would be google it. and yes its normal .
...some times i go in 2nd and do it..
