BIG BORE ATV'S

I went on a ride this weekend with a guy with a brute force and a sportsman 700. It was about 80 that day and we were going threw the woods. They both were over heating about every couple of miles. They would have to stop and spray out the radiator. I was just wondering if this is normal. Need less to say i am glad i had my foreman the fan only kicked on once.

Pretty normal for a liquid cooled machine to overheat like that when the radiator is plugged full of mud or what not.
yep totally normal i sell parts for a kaw dealer. Those rads are just big enought to cool that v-twin. If even a small part of them is plugged with mudor anything it'll overheat. Tell them to spray them out with a little bit more pressure....just not too much you don't wanna bend the fins. If you look between the fins you can see all the dried mud.
yeah they had little squirt bottles and were cleaning them out i had just never rode with anyone who had a brutefore or sportman 700 i was just wondering if it was normal which i guess it is
As with any liquid cooled machine you must take care of the radiator. If you don't spend the extra time it takes to thoughly clean the radiator they will overheat. We ride trails which contain a little bit of everything from mud to dust and we have went as much as 90 miles with liquid cooled atv's and had very little problems.
it is a very common for liquid cooled 4wheelers to over heat, especially the v-twin bikes like the brute. a good way i found to clean them out is, the fire extinguishers that have water in them that can be refilled. whenever i am going on a big ride that lasts for a couple days i bring one of them and leave them at camp, it works really well. all you need to refill them is a air compresser and water, i have passed this onto other people and they thought it was a good idea so i thought i would tell you all about it.

That's the life of owning a big bore!!!!I'd rather a Honda over any one of them.The only other bike I would get is a Grizzly 700(and sell the power steering unit)
more power more problems....

i rode with a guy the other day who had a brand new 2008 CAN AM 800.

jet kit, hmf exhaust, k&n filter, snorkeled and lifted, with 29.5 outlaws on chrome rims.

the bike was down ride beautiful. BUT, he got stuck in every hole we came to.

there was a lake we had to cross, everyone made it across, except for him, the whole time he had white smoke billowing out of one of the snorkles.

then he had to stop and drain water out, but what i was getting to is that he had a 12volt sump pump, he plugged it into the access. plug and dropped it in a clean puddle and used it to spray the radiator down.

i have to admit, that thing sounded like a small block chevy with dual exhaust at a tractor pull. but i could still ride circles around the guy when he was stuck. i would have taken some pics, but he got so pissed when i grabbed my camera i didn't want to risk it...

Those old fire extuinguishers are the bomb! You can literally soak a person from head to toe in about 2 seconds, not that i've done that!

What I do with my wifes brute radiator and my oil coolers on the honda is between rides I flush them really well with the garden hose, until there is clean water coming out the back of the radiator.

A great thing to do is take a bilge pump, wire a cig lighter on it for power and you can use it with some hose as a washer on the trail.
