3.5kg removed

I started work on fitting the fireblade seat unit, when i got to this point i'd already cut off 1.3kg:

But I still couldn't get the seat on, I'd needed to have cut the subframe right up to the tank mount, which would have resulted in lots of steel fabrication work to get the seat on... so i figured  I've now got an AC/DC tig so, I could just cut the whole lot off, save even more weight and fabricate a complete replacement out of aluminium. 3.5kg's removed looks like this:

I also trial fitted the fireblade tank cover, as you can see it reduces the distance to the bars.  I'm not sure if this is a good idea so have decided not to play with this for now:
