There's a few different M8 conversions showing up now.
I thought this video showing the Frame mod's would be interesting if you haven't seen it .
It's a little bit sad to see the frame chopped to shit, but that's progress !

I've tried a few times to open that kleen link and just won't play ball however the top vid was good.... Is it still an fxr after that, I get it, you need the room and the mount points so you gotta do what you gotta do but the M8 is counterbalanced, surely it could be solid mounted or even rubber mounts created that don't require the frame to be chopped up, mounts and gussets are fair game but down tubes! 

Yeah its a massive undertaking a little impractical if you ask me. That motor is coming out for any kind of top end maintenance.... its already a pita on my Twincams let alone that. 

Also, the M8 softail is so good that it kinda defeats the purpose for me a little. I can assure you there arent any currently in Aus haha.

Somebody was making an FXR frame for m8 motors... mightve been Yaffee? 

Yes, you'd need to be really keen to take on a project like that, and have a good wad of cash .
