I was able to hook up the Jagg 10 row cooler useing the HD adaptor and some unqiue plumbing. Temps stayed the same as with the HD Premium cooler. so unless the Jagg filter adaptor allows more oil to go to the cooler, do not waste your money, side effect is it forces more hot air from the motor to your leg. This is with the Jagg 10 row vertical mount cooler. Unless I can find a way to make more oil flow thru the cooler, I guess I will have to live with the temps. as the majority of the oil on these 07 up bikes flows back to the tank without going thru the cooler. Lesson learned. Doc
I would consider the Jagg cooler to be a system and would want to use their adaptor before writing off the product. Harley's design is very limiting, and while I don't know if the Jagg is much better I am assuming it can't be any worse. You may also want to consider how you have your crash bar plumbed into the whole system. I believe you said earlier it was in parallel, and if that's the case it may be robbbing flow from the cooler due to tubing size and lower restriction. And yes, placing a radiator or oil cooler up in the actual air flow will cause hot air to flow onto the rider. When we all get to ride the new water cooled Harley's in the near future, all the current talk about heat will be part of the "good ol' days". I still remember way back to my first water cooled bike in 1982; when that fan kicked in while sitting at a light it could get downright toasty.

PS. Doc, trust me I fully understand how some things can get under your skin until you feel you just have to do something. But I really think you're worrying and stressing too much over this oil temperature business. The design of the engine is such that 230°F is considered normal oil operating temperature by the MoCo. That is with the bike cruising down the road, not idling in traffic, and at standard ambient temperatures. When you throw in those 90° and up ambients you get where you are, I can see where 240°-250° oil temps would be common. Just keep using the best quality synthetic oil and try not to worry about it. Just think how many folks are out there right now without a gauge and just enjoying the ride (now you know why I don't have an oil temp gauge mounted, btw).
