PWR makes a nice rad for the 250r, $380 is as cheap as i've seen it though. i'll get some measurements and see how close the r and dale rads are. but mud clogging the rad is, IMO, the real problem. all the slop from the front wheels goes right onto the rad. you know that Randy uses the screen and hasn't had any trouble, but it didn't work for me. what did work was using cardboard to go from the rad shroud to the frame, behind the shock and up to the front of the machine. ghetto as ****, but works. air still gets to the rad. and the fan can still pull air through since the fins aren't packed with mud. could even go with a larger 8" "pusher" fan mounted infront of the rad(summit racing DER-16508). toggle switch it with a water temp gauge and it'd be gold.
I like it. Keep the cooling ideas coming. I was going to start a thread asking for suggestions on additional cooling, as I thought this was somewhat of an issue with the Dales. But, cdrookie is right, we need to find a way to keep the mud off the radiator first. I like the oil cooler idea. That is one of the few areas that have not been addressed on the Dale.

the big pusher fan is a good idea. the radiator its self is not the cooling problem, simply airflow and being restricted so much by mud. another idea would may be to elemiate airflow almost completely with some sort of an air dam and use just a fan for airflow. cooling would rely on just a fan, but it would work much better than the radiator just getting blasted with mud, because if it is covered with mud no matter how fast you go, or how big your fan is, the radiator is not going to get rid of heat. same thing goes for an oil cooler.

In my opinion number one cause of overheating or percieved overheating(coolant coming out of bottle)these caps come loose when the plastic bottle gets hot.There were a lot of overheating rumors/cases about two or more years ago.This was suggested and problems never really surfaced again till now.Note the hoseclamp.

Here is a great post from the experts.Kind of conflicting views though!
