I dunno know, but you're sticking with the Harley option due to the available warranty, which is important due to the reliability issues, especially with the 110. Further, you know the take away is a hotter, and less performing motor to boot??
If S&S doesn't have anything, the other guy said Jim's does, that I'm sure has a warrany - no doubt shorter, but will give you tremendously more power, drivability, and has a much better track record regarding reliabily and durability?
I not sure if following the sticking with the less reliable, lower performing option, just because of the warranty, makes sense, when there is a superior option in all regards. Have you checked what Jim's warranty is? On the other hand, it is more money, but less in the long run, if you do the Harley route and in a year from now realize it's not enough, or worse, is unreliable - even with a warranty.
Just thinking out loud.
