What can I say Brodie, your right.It's not too bad but more is always nice.
Have you thought about raising the height of the tank?
It looks as if the top of the tank is below the top of the upper fork yoke.
If you were to make them level you may gain another litre or two without affecting the look of the bike too much.
I was thinking of lowering the rear of the tank to get it as parallel as possible with the seat line but to get another litre in the tank I am raising the front and lengthening it about 20 mm, should make it about 13-5-14.5 which I am much happier with.
