A big fin head would probably be the best bet....fins are out farther,catches more air,,venting the fender probably wouldn`t be needed then...depends on how/where you ride i guess...
I know for me,the oil cooler definately stopped the oil from turning charcoal black in 500 miles...that in itself has to be a good thing..
yeah I vented my fender taking into account that I almost never ride in mud unless I have to...
If I do for some reason I thought about adding screen mesh to the backside and glue it on
my fender is also shorter in the back than stock, its a modded crf250 fender I think
I wish I could find a tranny oil cooler like spuds that I could mount where the xr250 and xr400 coolers mount as that would be the best, protection wise and airflow wise
again spud congrats hope the cooler lasts and it looks like it works well so far...maybe just add a littel protection to the pipes and hoses so they dont get snagged?
