Change and refill oil and change oil filter, refill coolant to it's level with proper mixture. Run bike on idle for 10-15 minutes, do a burst of revs and run constant rev at 5000 rpm for 20-30 secs, watch exhaust pipe smoke condition and if temperature gauge indicates overheating. Let bike cool off and check oil and coolant state. If you see milky oil, oily coolant and reservoir going empty, you may have a cracked cyl head walls. Happy hunting.

Hyo gt650r 06 Noticed bike is always running hot after short rides. Checked coolant and no coolant keeped topping it up. Haven't noticed any coolant dripping so checked engine and oil is milky. What do I...

Take the head off and take it to a machine shop where they can check and adjust everything. cost is normally around 150 for the machine side and and get a upper gasket kit which includes the head gasket it's a lot better to do this than to just replace the head gasket and the plus side is you only have to take it apart once
