Extra oil amount - Not too much. It's just like all other oil coolers that there's extra oil to be in the engine & cooler. Most coolers (stock, Ultra, Oil Bud) are generally the same size.
I couldn't tell you about the jiffy stand. My guess is that the stand would need to come off to install. But once installed it is completely out of the way. I guess it wouldn't work if the jiffy stand clamps or bolts to the frame on the inside.
Temp'wise - Even in cooler weather I'd hit 190*/200* with the Ultra. My last ride I didn't even come close to 170. Mind you, even with the UltraCool's fan running in normal highway speed I'd still hit 220*230*. In bad traffic it's get close to 290*. I'll let you know more in the middle of the summer. But I am very optimistic!
I don't mean to slam UltraCool. Just stating what worked/didn't work for me.
