my 12 is over heating ,the fan is coming on i have power commander 3 usb custom map,i can let it idle in garage for about 20 minutes come out and temp is up there then when i start to ride is go down til im at stopping position,also when it heats up clutches starts to slip

 

[bbhzx12]

Have you changed the coolant?

 

[bighens12r]

gonna try and do that this weekend

20 minutes :shock: sitting there at idle will do it. Not enough air flow, even if the fan is running. When you go riding, it goes down . . . because of the air flow. That is part of it. could be other things contributing.

normal

Clutch slippin prolly a goner..

I definatly would not let it idle so long also, maybe 5 minutes if it's cold but I don't even let mine idle that much. I would change the coolant, but the guys are right it sholdn't idle that much, nothing should idle that much.

 

[lie2me]

my '03 will overheat @20 minutes. Lot of motor to keep cool while sitting still.

 

[bighens12r]

thanks bros i was getting to the point to were i almost traded it in for a Busa lol

 

[redline]

yeah

Yeah I would not let mine sit and ideal for 20 minutes :shock: Mine get's hot when I stop at a red light... :lol: And mine has only 20,000 km's on it. I would change the coolant 50/50 with water wetter thou, will make a great difference I think it cools it down about 20% if I remember correctly... best of luck

 

[dcuttin]

they are some after stock fans made of metal (not sure if aluminum or iron) that will give you a better air flow at idle situation keeping the temp at 75 % of the reading scale.

20 Minutes! :shock: take a look at the manual is warns against letting the engine idle for too long. 5 minutes absolute maximum. I let mine idle for about a minute, then ride off - gently until the temperature has reached normal. THEN open it up :twisted:

I haven't found a reason to let it idle for 20 minutes, but after an oil change i do let it idle close to 10 minutes and have not had any problems with it overheating or even coming close. I have also never had heating problems at any traffic light stop even during the summer hot months. The only time I was worried was at laconia, were it's a very slow walk to the activity area in 88+ degrees for about 5 miles. At that point everything gets shut off for a period of time.

...............Idling 20 minutes :?: why so long ??? 5 minutes at the most should be all she needs to warm up. When's the last time you checked your coolant ? When's the last time you changed your coolant ? How long does it take before your fan comes on? Stock fan or Muzzy ???

thanks guys very helpful info , i really love this bike and i have spanked plenty of busa,10's and gxr1k's ,since i've moved here to Hawaii i ride maybe once a month i just did nt want to get on it and start cramping it but ill take your advice and i'm gonna flush it this weekend and go 50/50

 

[Aughtsix]

i'm gonna flush it this weekend and go 50/50

My opinion - DON'T.

Especially in Hawaii...

If you absolutely can't sleep without antifreeze in your bike, use 75% distilled water (with water wetter) and 25% antifreeze. Tops.

More than likely you could get away with 90%/10% or even 100% water/water wetter as it doesn't freeze in Hawaii. ( I do believe you should have some in there though as a corrosion inhibiter and lubricant)

Antifreeze actually inhibits the heat transfer capabilities of water but it's a necessary evil in climates where it dips below freezing.


And for crying out loud, stop idling your bike so much. It ain't a genset...

 

[bbhzx12]

Anti freeze also protects from mineral deposits that occur if only water is used

That's why I always use and specify DISTILLED water...

And I don't make my living as a Chemist, but how in the world would antifreeze hold the minerals in undistilled water in suspension? Seems to me that if you're using undistilled water, no matter what concoction you mix in, the minerals are going to come out of suspension and deposit somewhere...

IMHO

 

[lie2me]

Distilled water has no mineral? I have to use de-mineralized water for scrubbing some of the electronics cleaning....not up to speed on destilled.
If its a dumb question, feel free to ridicule me.... 8)

Okay, that's such a silly question, your hair sticks up and your mother dresses you funny!

How's that? :lol:

Okay, seriously, the process (roughly) of distillation is that a liquid is brought to its boiling point, vapor rises from the liquid and is routed to a condenser where it is cooled and once again becomes a liquid. Only that which is boiled off (becomes vapor) is collected in the condenser. For instance, since alcohol boils at a lower point than water, alcohol can be separated from water by bringing the solution to a point above which the alcohol boils yet the water does not.

Anyway, when water is distilled, only the water vapor rises - the minerals don't evaporate and condense with the water. They stay in the first stage.

I hope this makes sense.
