I'm thinking I'd like to install a cooling fan to turn on during long slow uphill climbs,,,,any sugestion on where to buy one or is there one avaiable allready for a 300 fourtrax

Not sure the 300 has a fan or not. Many other models have an oil cooler and fan already [unless they are liquid cooled] and it will come on by itself if it gets too hot. Look up under the front bumpers and see if there is a fan in front of the engine. If there is one there, you don't need one.

If there is not one there, then you could probably find an oil cooling fan for another bike and mount it somehow.

Agreed^^^^ Most any small aftermarket cooling fan will work And just wire a toggle or pushbutton up so you can manually operate it when ever you need it, but usually if the quad didn't come with one they are not required the engines are already air cooled. but added protection never hurts

As I stated those engines are air cooled and they took that type of riding into mind when they built it. but adding a fan will definitely not hurt anything by any means. Go for it

If the bike has a temp warning on it, then it of course will tell you if it's hot. I agree that I'd probably like to have more cooling too, but it took me a long time to really understand thermal design on products, and to get my head around what might seem hot isn't really all that hot, thermally.

But, hey, put a fan on it. It won't hurt a darn thing. :)

An external oil cooler would probably much easier... no electrical crap to deal with.

hehe. That's totally up for debate. Electrical stuff seems to me much easier to deal with than trying to pipe the oil out of the machine and back in. A fan is a few wires and a switch.

In the big picture, they are both the same. A few pipes and a load. Electrically, the fan is the load and the wires are the pipe. Exactly the same thing. :)

Yeah I gotta agree with both of them on this one I can see the oil cooler that would help disipate some of the engines heat but so will the fan. but as Pain stated hot really isn't that hot. put an infra red heat thermometer on the head after riding you'll see that the engine really isn't that hot maybe 250 degrees at the most. the exhaust takes most of the heat out.

Use an oil cooler. It does GREAT on my 350X powered 250X...

I used a B&M Super cooler and fab'd up some brackets, shroud and grill.

Wow...what's with the hate on "electrical crap"? I'm thinking a fan would be easier.

hey guys you do know honda engines run better when they are SLIGHTLY over heated?? (KEY WORD:"SLIGHTLY") It makes it easier for the gas to be combusted. IMPO oil cooler isn’t needed unless the engine has oil squirters (and I’m almost 100% sure they don’t) Unless your running 10,000 plus RPM. Then I understand the need for the oil cooler. But as my sig. states I know my s**t when it comes to honda cars not so much for the atvs. So don’t take my info and carve it into stone plz. NORMALY an oil cooler is inplace to lower the donation temp of the combustion chamber...the oil cooler cools the oil down and then is shot through an oil squirter that is squirting oil on the bottom of the piston to lower donation temp for added HP and protection.

I run oil coolers on all of my turbo (20psi) race cars and it has nothing to do with any of that... it's to keep the oil temps down and the viscosity up! I'm really not sold on the idea that oil squirters are going to save anything when it comes to detonation temps that are WELL into a few thousand deg's...

Just FYI you're right about no oil squirters but there's a fair amount of Honda ATV's that came factory with oil coolers including the 350X motor that's in my quad...

If you don’t have an oil cooler on a boosted engine then your just plain dumb and I hope that engine blows the f**k up. I’m not directing this to you turbojerk I’m just saying in general.
Trust me I’m not new to boosted engines I have owned 3 boosted hondas. An I’m in the works on a new turbo set up that will be pushing 350-400whp daily driven. I’m just not sure on what turbo I’m gonna use yet...I’m in love with the GT-K line from Turbonetics

It is sooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooo f-in sexy!!
I’m glad they finally dropped the price too by almost a grand. It use to be like $2400 now it's down to $1600

Awesome now I have someone to talk boosted talk with now!
