714banshee380 Posted February 11, 2008 Author Report Posted February 11, 2008 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 Quote
wacko2000 Posted February 11, 2008 Report Posted February 11, 2008 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... Quote

350BANSHEE350 Posted February 12, 2008 Report Posted February 12, 2008 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 Quote

BigRed350x Posted February 12, 2008 Report Posted February 12, 2008 (edited) check for air leaks? explain 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. - Jared 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. - Jared Edited February 12, 2008 by BigRed350x Quote

BigRed350x Posted February 12, 2008 Report Posted February 12, 2008 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. - Jared Quote
Snopczynski Posted February 12, 2008 Report Posted February 12, 2008 Are you sure its jetted right? One easy way to make it heat, is running it lean. Quote
2strokespirit Posted February 12, 2008 Report Posted February 12, 2008 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.. Quote

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. Quote

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. Quote
