The part number is 1g253-73260. Assumed that if it fit Jacks D1105 turbo, it would fit my na D1105. However, Jacks engine was new where mine was an old take off from a Jacobsen mower. It seems Kubota went to a higher flowing coolant system at some point...
Well dang. If you have to go to all that trouble, there's no reason to use the Kubota part, you might as well adapt something that's the right size for your thermostat. I'm sure the junkyards, not to mention the parts houses, are full of them. I'll buy yours if you don't want to use it, and I'm sorry I lead you astray...I'll make a note of that on my Kubota page
I'm pretty sure your analysis is correct; there were some changes to the plumbing on the D1105 at some point in the model line's history. It makes more sense than to think they reworked it specifically for the turbo model.
BTW, +1 to you and 1055 re the motorcycle endorsement deal. Not that there shouldn't be some sort of endorsement for motorcycles*, it doesn't seem to be all that appropriate for tadpole trikes.
It just floors me that in Oregon, a 16 year old kid who can pass a simple (and simpleminded) written test, and is doing well on his cocaine route, can take his money to his Hayabusa dealer and have a 180 mph accident on the way home.
