my mate has a 05 600rr stunt bike... the fan is wired direct, themostat is taken out and rad is full of coolant , but the bitch keeps over heating even when just doing circles, head gasket ant gone... are they known for this or does any of you lads have a solution..cheers

 

is the fan on the right way round ?
know daves bike kept doing the same thing for ages, then he realised the fan was the wrong way round, since putting it right i dont think its overheated again

 

some times no thermostat is worse then having one , the thermostat restricts the flow of coolant so it has time to transfer heat ...

if the coolant is moving too fast it doesnt have enough time to transfer the heat from the motor to the radiator and it doesnt stay in the radiator long enough to cool the heat it does have

 

dont be surprised if that bike stays in the 220 f range. 07 s have a significantly larger rad then 06s

 

but these ******* still get hot as hell. check everything that everyone mention they are all common mistakes. but i recommend a full flush and put in engine ice. Also hook ur fan up to work with a switch. This way if your at a lot you can turn it on all the time to keep the bike running cool. I did the engine ice thing and it works miracles. I just have to do the fan thing now.

 

running the overflow bottle is important also ...

 

I think im gonna try to run a dual fan setup hollywood....my bike gets super hot. I haven't done the engine ice yet

 

Yea its makes a difference. The dual fan setup is next on my list 2. I was gonna do it a while back just got lazy with it. the RR run so good wen running cool. but the minute it gets hot the idle goes crazy!

 

hondas overheat more than others (imo) i would stick the thermo back in, check the fan is pulling the air through the rad and not trying to push it, and also go for a twin fan setup.
Thats how i used to run the old mothership (929)
