How to make it run cooler?

[714banshee380]

I would say that that grill has to be blocking about 90% of the air flow. Might as well put a pice of carboard over the entire radiator.

 

 

It's not as bad as it looks the radiator does block a lot of air but

 

If the sun wasn't shining on the chrome the air pockets would look alot bigger

[wacko2000]

When you change the impeller, are there any gaskets that have to be replaced?

My whole motor just got rebuilt 2 months ago, all new gaskets throughout...

yea i bet thats ur problem..

thats y i like my stock grill

[350BANSHEE350]

honeslty change the freakin grill its useless unless you in the winter so much problem there

check for an air leak if it isnt jetting then thats your problem (check compression, plugs, air leak)

no mattter what you say, unless you do a proper plug chopand show us, then you are lean

my stock bike in 100 degree weather with no air flow revving the crap out of 1st gear with 6ply mud tires on through a swamp for about 30 mins none stopfull throttle is the only time it over heated

 

wacko

you should change the water pump cover gasket and clutch cover gasket

15$ of gaskets

With your engine running at idle, take a can of carb cleaner and start to spray around all your gasket and sealing surfaces one by one and listen for your engine to bog down. Also, on the stator side, remove your cover and spray around your crank seal. Head, plugs, base gaskets, reeds, intakes, around your carbs, all the way back to your filters.

 

Do you know how to do a proper plug chop? Check your jetting via plug chop technique at full throttle, 3/4 throttle and one at half throttle since that's where the majority of banshee riders spend their time and more than likely where your problem is.

 

You could try going up a main jet size and go for a ride and see if you still experience the same problem. You might be right on the very edge of perfect jetting, but still on the lean side. If you go up a size or two it would put you a little more rich and might be a POSSIBLE solution. Maybe close up your air screws a quarter of a turn and see what it does.

edit: forgot to add... only do 1 jetting change at a time and ride it and see if the problem persists. I'd do the main jet up a size or two first. Then richen up your needle a clip position and see how it does, then the air screw last. See if any of that helps the overheating problem. Once you have totally eliminated jetting as a cause, then move on to better cooling options.

 

Oh yeah, what coolant are you currently running? 50/50 mix of antifreeze and distilled water right? If you are running pure water or pure coolant it could cause overheating issues.

I am currently running pure peak coolant.... no 50/50 mix stuff

That's your problem! Try and mix it 50/50 with some water and see what happens! The green shit (ethelyne glycol) is only supposed to be to prevent freezing, slight lubrication properties, and helps with the cooling, but only when mixed with distilled water! It doesn't cool worth a damn when put in your cooling system alone. Try and mix 50/50 with distilled water and coolant or buy a jug of the pre-mixed stuff from your auto-parts store. Give that a shot and see what happens.

Are you sure its jetted right? One easy way to make it heat, is running it lean.

[2strokespirit]

You dont seem to be listening! Its not a cooling problem, its your jetting!! A properly jetted bike will run all day long as hard as you want to run it in temps well over 100. I know I've had more than a few gas bikes and ride in temps over 100 all summer long. CHECK YOUR JETTING! Correct your jetting problem, them worry about getting better cooling components.

 

 

I don't want to start an argument, but just want to inform some of the guys here, I don't know how hot it gets in the states, but I live in desert area in Southern Africa, in the summer at X country when the bike gets enough air, it just can not stay cool enough, do nott even wanne talk about slow trail riding, it will only stay cool at a cruising speed. There is nothing wrong with my jetting or cooling system, engine ice, nothing can keep it cool except and oversize radiator. ALL the guys, yes ALL the guys here that runs in the National enduros put an oversize radiator on their bikes, its one of the first mods they do.. On a banshee its not the radiator that is the problem, but the airflow, the gastank is close behind the radiator and restrict airflow, yes the stocker would have worked if it was mounted on a less restrictive place... I do agree with you that this guy MAY have (MAYBE) another problem... but a stocker won't run cool here on a HOT summers day (which is the whole summer), unless my temp gauge or laser gun is faulty...

This has been experienced..

hey jared... since i just used up my last bit of peak

 

should i just buy some engine ice and 50/50 that with some distilled water?

 

and when i put collant half way in the overflow should i 50/50 it in there also?

Egine Ice isn't made to be mixed.. It comes ready to use. Just dump it in and go.

 

You can buy regular anit-freeze already pre-mixed at 50/50. Its a lil more money. Or you can get the cheap stuff and mix it yourself.

oh but they said you gotta flush out your old stuff before you put it in

[shanYE west]

Yeah. Just drain out all the old stuff and Dump in the Engine Ice.

How hot you talking? My buddy and I ride in our dunes when its up around 110 to 120 degrees and he still has a gas engine and we've ridden for hours on end and he's never once had an overheating issue with his. I dont' worry about mine running on methanol keeps it plenty cool.
