I have lots of experience with fans on my Kawis and the first thing I recommend you to do if your fan is running alot more than normal is to get your cap checked. The other thing is some frequency thingy like the ones I use from reds650 will make the bike run quite a bit cooler and I tested this too. Adding water wetter worked great on my 650 but not as effective on the 700. I also have a switch on both bikes so I can turn my fan on when I want to, I'm more concerned about my fan not comming on than running too much. My fan doesn't run long even when it's hot when the key is off, and when it does I order a new rad cap and really clean the rad out. Also I turn my lights off on hot days when the fan is running too. I also take both side covers off and hose the rad out from both sides back to front after each trip out religiously and I do a very good job too. Also I found that when your bike is running hot at low speeds if you remove the top plastic over the air box cover it will help in cooling expecially if you are stopped it allows heat to excape. I also blocked, made the inner plastic splash gaurds bigger on the 700 so the mud etc. from when I hit the puddles the mud from my tires don't go up between the frame and the plastic and clog up my rad so I would not recommend removing the black plastic, if you do... do it with caution. Lower grade of fuel also should help in cooling, (I was told this I don't the truth of this). Also being carefull and aware of the heating issue on the bike will also help ie, I don't let mine just sit and idle long at all, I use my kill switch.

 

KAWI650, what is this frequency thingy you are talking about?

Terry, its a module.

Also, my way of thinking on the inner fender deal is that the fenders keep more hot air around the engine where as if they wasnt there the hot air could escape better. Sounds very very logical to me.

 

KOD I agree it will allow more heat to excape however it does also leave the rad more open to get clogged up is the only thing I see about that. Also the design of the black plastic behind the rad also could be removed/ modified. Even thou , kawis way of thinking was to let the hot air be forced under the machine at higher speeds and the plastic builds the wind tunnel for that.

 

NovaKaw650 has a good point. Some early farm tractors were water cooled and had no water pump. There are also some wood burning heating systems that work that way. You kinda beat me to that reply but still glad to see that info out there.

 

ive left the radiator shrouds on for protection but removed the two inner shrouds that sheild the front cylinder head..my fan runs far less now than it did...

 

The inner fenders do offer some mud protection but a person has to evaluate how much mud its actually blocking according to the way they ride. Im going to check the cost of the inner fender mud guards and see how much they are. If the cost is reasonable I may cut the inner fenders right between where they attach to the radiator and the springs . This will still provide for decent stick protection "which is all im worried about" and still let the hot air flow out at slow speeds from around the engine. Also the fenders that attach to the floorboards can also be trimmed up near the front head. Just use some common sense when trimming. For example, on the right side you probably wouldnt want to cut away the little box that guards the key switch.

Go out and look at the inner fenders and you will see what Im talking about.

 

no it probly wouldnt be wise to cut away around the ingnition swtich but that is covered by the two larget radiator shrouds..all ive done is taken the two small inner shrouds out.

 

I took the sides off all together! (See photo in Profile) I only have the bottom and the small peice that gos around the steering steim. The quad seems to run cooler? (I have never had an over heating problem those.) there is more then enough protection with the sides off IMO, for my style of riding. If one was more into mud and swamp riding I would leave it the way it is to help stop Mud and Muck. Most important! make dbl sure that rad is clean... Just my 2 cents! ~coop

I think my next buy is some 2in black exhaust wrap, that should help with cooling as well?
