That is a good thing to keep in mind for sure! I do have already have the k member to switch to an 8 ... but I know a lot of other things follow along with that ... so It'll be a while until I am ready. But I'd just be going for more power and better sound. I'm just wanting a nice cruiser that sounds a looks good. :)
K frame swap if fine, but they make mounts for the biscuit style for about 65 bucks. Just another option. Lots of options for this swap, I've done it personally more times than I care to remember LOL.
