Am a big fan of Giallo, but that's not the problem with the 1098/848's. It has more to do with the styling of the bike itself. If our eye travels from the front to the back of a bike, the Foundation Line is an "imaginary" line that our brain follows as we observe the design. In the 916/748 series, and to a lesser degree the 999/749 series, that line begins just below the intake "nostrils" at the front of the fairing, and moves aft from there, lining up with the bottom of the tank, and ultimately following the base of the seat. In the 916 especially, this line is uninterrupted, and offers plenty of options for mapping graphics, which either strictly or loosely follow that line.
In the 1098/848, the Foundation Line is a less well defined line, and more of a suggestion of the line if the eye follows the same path from front to rear. The bottom of the tank angles up from it's bottom forward edge to it's rear where it meets the seat. Your options for adding graphics which "follow" this are going to be limited. However, you DO have one very cool thing going for you with that bike... they seem to have employed what in automotive design is known as a Shoulder Line... which is typically a broad visual cue, again interpreted by the brain when observing a design, which moves uninterrupted through the design. In automotive design, this line typically begins at or just aft of the front wheel arch, and then moves to the rear.
The 1098 has a beautiful example of this... the vent on the side of the fairing shares almost the same angles as the side covers below the tank, which then visually blends with the sides of the seat and then terminates in those interesting panels on the sides of the tail. I bet you could do something really cool from the vent rearward that blends really well with that design feature.
P.S. Namor's is right... get rid of the huge exhaust shield. Go with nothing, or at a minimum, the smallest shield you can find.
