When we were out at Hollister I destroyed my fan in the mud pit and the shroud. I had to go to town to buy a new fan and since noone carried the original equipment fan I had to buy a flex fan. When we got back on the trail i was running hot not overheating but definatley hotter. I didnt have the bottom half of my fan shroud wich may have been part of the problem but what is the deal with these flex fans I thought they were suposed to pull more air. Is that just not true? Or is it only at speed because on the ride home it seemed to cool just as well and maybe even a little it better.
