Thanks for posting the feedback, Mike!
My oil cooler is mounted about 4 inches higher on the downtube than yours was.
Regarding the mud; I couldn't agree with you more.
If one is slogging through the mud, he doesn't need help from the oil cooler. If one is going to ride at high rpms, for an extended period of time after
slogging through the mud, wash the cooler off with some water.
