Well, I think you're almost there. It's been fun watching the metamorphosis of this project. When you have time, would you take a picture of the master cylinder for your brakes. I'm guessing it's got to be a bit bigger. Is it attached to the lever like the OEM?
Second, there's a few items left for you to do......! First, when looking at the side view, I'm thinking the custom seat needs to be more deep blue than gray. Maybe some lighter blue sewn into the seat top in the style of the paint scheme.
Third, I think the Pièce de résistance would be having the tire company put some blue dye into the rubber before pouring the mold. Wouldn't that be something unique?
Great job on this project and I only hope you're having as much fun riding and showing the R3 as we have been watching your project.
