Hey all, i am relatively new to the motorbike scene, i have a 2010 YZFR 125.

 

Recently the radiator coolant has decided to relocate its home to my cylinder chamber, i am going to strip it down and replace the gaskets, fingers crossed its all it requires, but do yall have any advice on what else should be replaced at the same time.

 

Engine oil seems to be coolant free for now, just changed the engine oil and filter 20 miles before this happened. Grrrrrr

i have also replaced the spark plug at the service.

 

so apart from the obvious engine gasket set what are other parts do yall think i should replace.

Hi there,   i would flush Radiator,  and do water pump,,[ seal etc,],   there has to be a reason why it boiled, ..

With any luck it's just a head gasket failure. 

Check when you remove it. If the headgasket looks sound you may have a cracked head. 

It's surprising as these engines are more reliable than time it's self unless abused to ridiculous levels or big bored.

Thanks for the reply blackhat250, got the engine out last night hopefully get it stripped this week. after taking the radiator off there was still a good bit of coolant in it so fingers crossed its not as bad as i first thought.

 

was expecting the water pump to have passed all the fluid  into the engine but the there was still coolant in the water pump so thats a good sign i guess.
