Default Oil Cooler Question

Putting the oil system back together and wonder what's the consensuses on location? I've seen them just above the fender and down by the regulator? I plan on adding a Jag? Tstat to it since we will end up in snow country and spring and fall can be pretty cold during the day, but for 2 months you really need a cooler.

any ideas?

No way I would want one installed down by the regulator. Too many unknowns on the highways to run over.

It wouldn’t take long for all the oil to be pumped out if something flew up and poked a hole in the cooler. It would be rare to happen....but still could happen.

I've had oil coolers mounted above the regulator and never had a problem, but I see what these guys mean, it could have something kicked up from the front tire, and on the down tube it would probably get cleaner freer air flow and work more efficiently

I have an older harley oil cooler, and in their infinite wisdom, it was made to be installed under the regulator. Probably works OK, but not the best location for sure. Any cooler is better than no cooler when you ride in Phoenix.

Oil coolers on my bikes,
Evo for over 60k,
TC for 32k,
M8 for 45k,
Not saying it can never happen, and I actually never heard of one having a problem,
where else would a ten row be mounted?

I was paranoid at first mounting them there, I keep a piece of 3/8" hose in the bag just in case.
