The bike must be completely cold, pref left over night.
Switch ign key on. Twist throttle completely open and then close it again. Switch off ignition key. (TPS re-set)
Switch ign key on again. Without using throttle, start engine. Let it idle for 15 min. Do not use the throttle. Watch temp, it should remain OK if your fan works. I have a large capacity fan that I aim into the rad, but I live near Upington. After 15 min, shut off with ign key.
Take it for a spin and be amazed.
