Coolant

[Mr.Sloth85]

I have a brand new 07 kx250f and this thing leaks coolant like no other. Not a few drops but like a puddle. This is my first bike and after a few rides i had to put more coolant is when my buddy bought his new 07 that same day and still has plenty. I thought it might have been just full, but when I refilled it, it did the same. huge puddle of coolant under my bike. It only seems to happen when I turn the gas off and keep the bike running after my day of riding. Is this a serious problem or is it common and is an easy fix. All coolant leaks from the hose.

 

[Mr.Sloth85]

Is this a serious problem?

 

[Moose]

Coolant leaks from the Hose? Are you sure it's not cracked or anything?

 

[Mr.Sloth85]

Ya I see flowing out of the hose.

 

[Moose]

wait, maybe i didn't understand that.

is it from the overflow hoses?

 

[Mr.Sloth85]

It is from the over flow hose. But it wasnt overfilled.

 

[Moose]

does it ever stop...or does it just keep going until the coolant is empty? sorry, i'm a noob at this...just trying to help out, because it's very seldom you'll find help this late at night.

 

[Mr.Sloth85]

Ya thanks. Help is good. It seems to just keep going. only when the bike is idleing though. Any idea?

may i ask why are you running your bike at idle with the gas off?...........maybe your overheating the engine and its just overflowing like its designed to?


if you not storing the bike for a long time just shut the gas off and forget about it,if you are storing the bike for a while just shut the gas off and remove the drain on the bottom of you carb and let it drain.

So dont run the gas out that way? My duddies do it and there coolant doesnt leak. Not that im doubting you. I wont run it idle anymore. Im noobish so I do what im told :bang: :coocoo:
Thanks for the replies. So you think its not serious

 

[Mr.Sloth85]

Ya this mx bike is pretty much trails only. But ill hit the track every once in a while. Thanks for clearing this up.

If I idle my CRF450R took long coolant will start to run out of the overflow. It sounds as though you are overheating it. If you want to emplty the carb, try turning the gas off as your riding off the track so that the amount of time spent at idle is limited. The new four strokes really need air flowing through the radiators to keep from overheating.
