Does anyone else's F4i leak alot of coolant while stunting? Im not sure if its during the wheelies or stoppies, but my bike leaks a shitload of coolant out. At first I thought it was the cap, but im on my second overflow cap and its still leaking. Is there an overflow tube that i need to cap off or something?

 

my boys did the same thing for a while never actually over heated just always kicked it out , he changed he fluid , sensor etc. never fixed anything , so he ended up just getting a diferent one and the new one doesnt do it , i was told it has something to do with the build up that radiators get with old fluid ( dried up inside ) and doesnt allow to fully let coolent run threw the whole radiator ! therefore spits out.

 

mine leaked at the overflow bottle cap all over the subframe and swing arm on the right side.

 

thats what mine is doing...the cap feels tight as can be but still leaks

 

i just ignored it. soon the amount in your system is perfect & nothing is in the over flow.. it is a over flow tank, not a reserve..

 

+1 .......that would be your answer sir

 

You could alway try flushin your system, and then when you refill your fluid, don't put any in your over flow .

 

it will puke alittle into the over flow if u top off the radiator.

 

mine leaks out the numerous holes in the raditor...lol

but pre holes on my stock f4i it seemed like the overflow bottle never had nething in it, and bike stayed at 190-220
