I tried to resist the temptation but I have to throw in my two cents worth.
It's got some awesome kit on it and probably is worth the asking price in 3rd party bits alone.
The designer looks like he really wanted to design two different bikes but only had the budget for one.
From the tank back, I find the bike really appealing.
Seeing the frame mods are irreversible, the bike needs to be resurrected by removing the tank and changing the bars. Fabricate a custom tank of similar shape but with with a lower profile.
I'd buy it to finish and keep because most of the hard work and money has already gone into it.
These photo's show the design aspects of some similar bikes which may have inspired the builder including an awesome little FZR.
