Big Twin Cafe Racer... anyone feeling brave?

... or nuts? I have seen all the Sporty's (both w/stock frames and "featherbed" (British) frames. What I'm looking to do is put the 95" motor from my 2001 FXD into something that doesn't weigh a ton! I know all the reasons some think Harleys shouldn't be anything but stock or chopped... but I've been down that road more than a few times. I saw a great TwinCam on the Kneeslider forum but I don't have the cash for something that pricey.

I'm wondering if anybody has put a TwinCam motor into a big, sporting Japanese frame or something equally daring (i.e. dumb in sane eyes!). I love Harley motors but I am not all that fond of the way their bikes handle. I have had Sporty's through the years but wanted a big twin motor (more aftermarket hop-up stuff available). So I got a Dyna thinking it was the only way to get the TwinCam motor in anything that didn't weigh so much. Geez, it still weighs over 600 lbs! Yes, the motor is mildly massaged (ported heads; Andrews cams; E-Series 2-1.... blah, blah...dynoed at 92 hp and 95 lbs torque). Still, with that lazy-ass handling and porky weight, it is a bit "ponderous" to say the least. I'm not dumb enough to think I can find a chassis (or chassis mods to the stock frame) that will make it into a Yamaha RZ 350 or anything... but still, must that motor be stuck in that semi-truck home it currently resides in? Ideas? Links? Should I seek psychiatric counseling????
