Wish mine was full fairing still.
Looks good, only thing I see I don't like is how that FI cage mounts to the rear subframe mount. If that's a stock sub and bolts the first drop will probably shear the Al bolts off.
Why use a good tank to dent? Well probably would have taken some time to sell the good one, then find a cheaper damaged one that's not too damaged that wouldn't require a good amount of welding and extra time. So in the end theres a chance you wouldn't save any money unless you found a good deal. That and you can't do anything like this on a non-dented tank.
