Well i can give you a good response that you may not no. On the honda rancher it's only 329cc engine with a new oil dry sump, it soppost to be totally different than the other honda atv's. With the small engine it can lose more heat also.

 

I have a cooling fan on my Recon and it really helps to keep it cool, i have it switch operated so when i know im going to be riding slow with high RPM i just switch it on! It really helps keep it cool in the winter plowing snow! I custom built the mounting brakets out of aluminum and i got the cooling fan off of a wrecked 84 Toyota supra, it was the fan that cooled the airconditioner condenser, but then i took it apart and sand blasted it and painted it black! its fairly larger than the fan on a rancher and can push alot of air! works great!!!!
