Coolant leak
 
2 Attachment(s)
I know there has been some people who have asked this. I just wanted to upload a couple of pictures, so people can give me an advice on it. Just so you know it only leaks when i hit or go above 11,000 rpm.

Thanks for the help

thermostat gasket?

I never thought about it. I was just hoping it was the water pump gaskets

it only has an oring to the block and the thermostat gasket.

I meant the water pump's o-ring and gasket. Where exactly is the thermostat located?

the pic you took is the thermostat cover.

No, the pictures he posted is the water pump (lower left side of the engine). The thermostat is under the tank. Just follow the 2 hoses that run from the top of the water pump up to the thermostat location.

My thermostat gaskets blew badly at some point [im guessing a track session?] and leaked all over the place. It left greenish residue all over the place including where it dripped past the water pump and hoses. It then sealed itself back up and never leaked again and never got the bike too low on coolant. I still replaced both gaskets :)

it doesn't leak seam like it's a thermostat problem. so either the o ring or gasket needs replacing or the entire water pump. Any other suggestions that i should look at?

Hey, how would you now your inspection hole leaks? i mean does just leak if the bike is off or it has to be running idle?
