Thanks for the pics & tips.
I contacted Moto specialties and they do not have a mock up of the 919 so no predrilling. But it sounds like I wouldn't want that anyway since it sounds like I might want to rotate them a little to avoid tank clearance issues. Thanks Motocycho for the advice, Plane (Pete) for the tape tip, nice avatar by the way, always liked that bike, and Motorwerks919 for the pics, they give me a good perspective on the riding position.
@tpirman - if you get those comparison pics I'd be interested. That may cement my decision.
