you should not need a oversized radi to cool your bike... a billet impeller and distilled water/redline water wetter,or engine ice and you should be plenty cool...spend your money else where.... if your having cooling issues you got problems elsewhere astockradi will cool fine...

I am from SA, its summer here and the outsize temp is over 40 degrees Celsius. I have a brand new 2006 banshee with some mods on, there is no way that this bike can keep cool when doing trails or cross country, not with a billet impeller or engine ice. I run distilled water and everything you can think of, i already tried, I have a heat gauge of good quality on my bike and it keeps in the 90(degrees celsius) and wil easily overheat when pushing over 8000rpm in top gear or speeds under +-40Km/h.

The problem with the banshee is not the radiator size, but the airflow, there is not good air flow behind the radiator, cause the fuel tank is in the way, the airducts in the fuel tank cover just aint good enough. The banshees can run real cool in stock form, but modifications(more power, more heat) then they start to run hot. Running hot is not dangerous, its just to close to the danger point. Like i said the problem is airflow, buying a bigger radiator, give more area for more water to touch and more air to touch, so you can solve this with i bigger radiator, even if the airflow is not good. but if the banshee's same radiator was open and had no abstructions it would not be a problem to keep the motor cool under any riding conditions. I don't know how hot it get where you guys are riding, but thats my experience. Have you ever run a heat gauge to check enjin temp? a Freind of mine had the same problem here and bought a pro design oversize radiator and all his problems are gone. He had a billet impellor with in line coolers and everything and it could not do the job. I have no other option but to go for a oversizr radiator as well. Just though I'd chare my experience.

First off,get yourself a spare plastic radiator grille.I made air deflectors out of an old grille that really helped to redirect the air coming into the radiator and forces it thru,rather than going around the sides.I mounted the deflectors in the existing screw holes for the grille cover.If you match up the diamonds you'll see they just make the spacing for the bolt holes.Use your imagination.The angle of the solid plastic wing to the platic diamond mesh is perfect.Hard to explain,easy to figure out when its all in front of you.You cant even see it unless you really look into radiator cover.

 

You will also need a billet impellar,huge waterflow improvement.A cool head is better money spent vs a radiator.The cool heads really make a difference,not to mention the heads themselves have double the aluminum of a stock head.More aluminum,more heat dissapation.

 

I've ran a temp gauge for years.160-180 getting good airflow.180-200 with very moderate.200-220 with minmal.

I've maintained 200-220 for extended period of time with no problems.Even with a temp gun,220 at the head only shows 150-160 at base of cylinders.Thats were the damage is done from overheating.

Okay so some say a bigger radiator some say cool head. I guess no one REALLY know which one is better. Might as well get both, right!

You wont believe this, but i have a pair or air deflectors, I made them from a alumnium sheet, polished, looks real cool. It was the first trick that I tried, mounted them the same way, with the grill's srews. Did make a little differance when riding real slow, I will buy the radiator and head anyway, cant keep the bike too cool can you?

but thanks for the help.

I think the cool head will make a bigger difference, but I won't arue with your logic, it surely won't hurt the engine to run a bigger radiator, or cool head.

 

EDIT: I don't have any cooling system mods, and I'll run her hard on a 90* day, and then putt around on slow trails. Never had a problem. The engine in my 01 lasted 4 years of somewhat regular of riding before it started to kick low. Just change your coolant and fluids often enough.

the cool head isnt going to do much to cool your motor after you reach running temps... to get better cooling the big radi would be the way to go but like said you should have no issues with cooling on your stock radi...

 

 

 

 

sorry 2Stroke but id have to disagree with you that a moded banshee has cooling issues... i have alot of mods done to my bike and run a stock radi with a billet impeller and water wetter i havent had one signle problem with the heat...

 

im not sure how hot 40 degrees Celcius is but if its not over 110 F then you got some issues...

Wow...this guy is in Clarkston, only 1/2 hour from me...should see what he wants for one of those radiators.

Then again, my 4 mil wasn't close to overheating on stock rad, straight water and a billet impeller...

 

The last one got up to 200 bucks or so...

 

Toomey used to sell a bigger radiator, but...I don't see it on their site anymore...

thats the guy I got mine from, for the '01, couple of years ago. done alright by me and I've had it in for like 2 1/2 years now. just shot it w/ some hi-temp black grill paint before I put it in( pesonal preference). was supposed to go riding regularly up on a local mountain that was notorious for making bikes( especially Shees) over heat. just never panned out.

Last weekend the air temperature was 46 degrees celsuis it is 115 degrees F. There was no way they bike could keep cool on that day while we were doing cross coountry on long straights at abour 8000rpm. I am not arguing, but my friends New LTR 450 fan just did not switch off and was running constantly, The one guy on a 2006 YFZ said that hid fan just never came on in almost any condition, and his fan was running as well, so we spoked about how hot it must be, the air that pass the engine and exhausts are so hot that my legs get irritated. We had to reduce speeds to a nice cruising speed for the bikes to run cooler. Like I said, in SA a modified banshee will not run cool enough in the summer when running cross country at high speeds with a stock radiator.

IMO when the temps start reaching 95+ I stay home. Its not good to run these motors in the middle of a heat wave.

Avg running temps should be lower. Reason is they hold and flow more coolant and have less resistance = greater flow. This removes the heat quicker and we know quicker heat removal means a lower avg motor temp. Same reason aftermarket impellars work so good. They force the coolant through faster.
