Glad I've got it now and will sure help come next spring when our temperatures starts on the way back up.

What if it's set to come on when the oil temp is 150? Just saying.

Maybe you can find some documentation that shows when it comes on, or maybe just measure oil temps and tell us when it turns on the fan. Just curious.

Again, no doubt the fan helps, but is it actually needed? HD states its for parade duty or long idle use.

That said the temperture data I posted shows that it helps and after all the money we spend on these bikes, it's very cheap insurance in my book.

Sure, giving enough time it should end up in the cooler at one time or another but that doesn't do much good if the oil has already been pushed to hot and is breaking down. Once that occurs mixing bad oil with good oil is even worse! Were just in the learning phase of things and until all the data is gathered we will not know for sure. All I can say is it's not looking good based on the heat readings so far from the engine temperature sensors and from head temperature readings. Once we have the missing piece, which is Oil temperatures, things will be what they are. If it needs and addition oil cooler I will install one, others can do as they wish as its there bike.

The new fan assist cooler kit came with new hoses, My bike is brand new so we felt no reason to change them, have a worm drive clamp at the cooler end,and the upper hose ends crimp on clamps were left as is.

Its my intention so swap out the worm drive when I get the bike home.
